## Security

### Security Headers (B — 75/100)

*7 of 10 headers properly configured*

- **[PASS]** Strict-Transport-Security is properly configured
- **[PASS]** X-Content-Type-Options is properly configured
- **[PASS]** X-Frame-Options is properly configured
- **[PASS]** Referrer-Policy is properly configured
- **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
- **[PASS]** Content-Security-Policy is present
- **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.
- **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
- **[PASS]** X-Powered-By header is not present
- **[PASS]** Server header is present without version info
- **[PASS]** Domain is in the Chrome HSTS preload list (status: preloaded)

### Content Security Policy (A+ — 100/100)

*9 of 10 CSP checks passed*

- **[INFO]** Raw CSP policy
- **[PASS]** default-src directive is set
- **[PASS]** No 'unsafe-inline' in script source
- **[PASS]** No 'unsafe-eval' in script source
- **[PASS]** No wildcard in script source
- **[PASS]** object-src falls back to default-src
- **[PASS]** base-uri is properly restricted
- **[PASS]** frame-ancestors directive is set
- **[PASS]** form-action directive is set
- **[PASS]** upgrade-insecure-requests is enabled

### TLS & Certificates (A+ — 100/100)

*TLS 1.3, 7 checks passed*

- **[PASS]** TLS 1.3 is used
- **[PASS]** Strong cipher suite is used
- **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance.
- **[INFO]** OCSP stapling not enabled — Without stapling, the browser performs a separate OCSP roundtrip on first connection -- adding latency and leaking the visited host to the CA. Enable OCSP stapling on your TLS server.
- **[PASS]** Certificate is valid (expires in 43 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 2 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (A+ — 95/100)

*3 cookies analyzed, 8 checks passed*

- **[PASS]** Cookie '_gh_sess' has the Secure flag
- **[PASS]** Cookie '_gh_sess' has the HttpOnly flag
- **[PASS]** Cookie '_gh_sess' has SameSite=Lax
- **[PASS]** Cookie '_octo' has the Secure flag
- **[WARNING]** Cookie '_octo' is missing the HttpOnly flag — Without HttpOnly, this cookie can be accessed by JavaScript, making it vulnerable to XSS-based theft.
- **[PASS]** Cookie '_octo' has SameSite=Lax
- **[PASS]** Cookie 'logged_in' has the Secure flag
- **[PASS]** Cookie 'logged_in' has the HttpOnly flag
- **[PASS]** Cookie 'logged_in' has SameSite=Lax

### Cookie Hygiene (A+ — 100/100)

*All 3 cookie(s) pass hygiene checks*

- **[PASS]** All 3 cookie(s) pass hygiene checks

### WAF / Bot Protection (B — 75/100)

*No WAF detected via response headers*

- **[INFO]** No WAF detected — Response headers don't match any known WAF or bot-management product. Sites exposed to abuse (login, signup, payment) typically benefit from a WAF such as Cloudflare, Akamai, AWS WAF, or Imperva.

### security.txt (A+ — 100/100)

*Vulnerability disclosure policy*

- **[PASS]** security.txt found

### Cross-Origin Tab Safety (A+ — 100/100)

*All 11 new-tab link(s) carry rel=noopener*

- **[PASS]** All 11 new-tab link(s) carry rel=noopener

### CSP Inline-Style Readiness (D — 60/100)

*119 inline style attribute(s) detected*

- **[WARNING]** 119 inline style attribute(s) detected — Each `style=""` attribute forces `style-src 'unsafe-inline'` in any Content-Security-Policy, which negates most of CSP's XSS-mitigation value. 119 inline style(s) is high. Affected element types include: body, div, span, svg, ul. Move styles to a stylesheet; use CSS custom properties for runtime-dynamic values; or adopt a nonce/hash CSP policy. Most teams take the stylesheet path because it's also a maintainability win.

### Trusted Types (XSS Sink Hardening) (B — 95/100)

*Trusted Types not enabled*

- **[INFO]** Trusted Types not enabled — Trusted Types (CSP3) is a Chrome 83+ defense that requires DOM-XSS sinks (innerHTML, document.write, eval, ...) to receive a typed-and-sanitized value rather than a raw string. Adding `Content-Security-Policy: require-trusted-types-for 'script'; trusted-types default` neutralizes most DOM-XSS even when a payload reaches a sink. Adoption is currently ~0.1% of pages so this is informational; a roll-out usually starts in report-only mode.

### Bot Challenge Detection (A+ — 100/100)

*Scan reached real page content (no bot-protection interstitial)*

- **[PASS]** No bot-protection interstitial detected -- the rest of the report reflects the real page

### Soft-404 Detection (A+ — 100/100)

*No soft-404 patterns detected in page title or headings*

- **[PASS]** No soft-404 patterns detected in page title or headings

### Empty Page Detection (A+ — 100/100)

*Page has substantive body text and no placeholder / template-leak signals*

- **[PASS]** Page has substantive body text and no placeholder / template-leak signals

### Geo-Restriction Detection (A+ — 100/100)

*No geo-restriction signals detected -- scan reached the page from an allowed region*

- **[PASS]** No geo-restriction detected

### Maintenance Mode Detection (A+ — 100/100)

*No maintenance-mode signals detected -- scan reached a normal page*

- **[PASS]** No maintenance-mode signals detected

### Subresource Integrity Adoption (F — 30/100)

*0% SRI adoption (0/36 third-party resources)*

- **[WARNING]** SRI adoption: 0/36 third-party resources protected (0%) — Of 36 third-party `<script>` / `<link rel=stylesheet>` resources, 0 (0%) declare a Subresource Integrity hash via the `integrity=` attribute. SRI binds the page to the exact bytes of the third-party resource: if the CDN is compromised, attacker-modified bytes won't match the declared hash and the browser refuses to execute the resource.

Missing SRI on (first 5 examples):
  - https://github.githubassets.com/assets/light-707b19cf061aa459.css
  - https://github.githubassets.com/assets/light_high_contrast-fc4b867e16562d12.css
  - https://github.githubassets.com/assets/dark-93f3c6b445d800ff.css
  - https://github.githubassets.com/assets/dark_high_contrast-49511e11e3ed53a8.css
  - https://github.githubassets.com/assets/primer-primitives-9f1db623a2d85734.css

Fix: add `integrity="sha384-..."` and `crossorigin="anonymous"` attributes. Generators: srihash.org, or in-browser via `await crypto.subtle.digest('SHA-384', bytes)`. Cache-bust the resource URL when you change versions, since the integrity hash will mismatch with old cached bytes.

### CORS Depth (A+ — 100/100)

*No CORS response headers -- the resource is same-origin-only by browser default*

- **[PASS]** No CORS response headers -- the resource is same-origin-only by browser default

### Permissions-Policy Granularity (C — 60/100)

*No Permissions-Policy header set -- powerful features (camera / microphone / geolocation / payment / USB) default to allow-on-same-origin*

- **[WARNING]** Permissions-Policy header not set -- features default to allow-on-same-origin — Without a `Permissions-Policy` (or legacy `Feature-Policy`) header, every powerful browser feature defaults to its spec default policy (typically `self`). A third-party iframe injected via XSS or a misconfigured embed can still request access to the user's camera, microphone, geolocation, payment APIs, USB devices, etc. Explicitly deny features the page doesn't need:

```
Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=(), usb=(), accelerometer=(), gyroscope=()
```

Features the page legitimately uses can stay enabled with `feature=(self)`.

### Referrer-Policy Strictness (D — 50/100)

*Referrer-Policy is `no-referrer-when-downgrade` (leaky -- legacy default that sends full URL cross-origin on HTTPS-to-HTTPS)*

- **[WARNING]** Referrer-Policy: `no-referrer-when-downgrade` -- leaky -- legacy default that sends full URL cross-origin on HTTPS-to-HTTPS — The legacy browser default (Chrome <85, Firefox <87). Sends the full URL (path + query) Referer on cross-origin requests as long as the protocol doesn't downgrade. This means session IDs, tracking tokens, search queries, etc. embedded in URLs leak to every third-party HTTPS origin the page links to or embeds. Switch to `strict-origin-when-cross-origin`.

### Source Map Exposure (A+ — 100/100)

*Source-map probe didn't run on this scan*

- **[PASS]** Source-map probe didn't run on this scan

### HTML Version Disclosure (A+ — 100/100)

*No software-version disclosures in HTML*

- **[PASS]** No software-version disclosures in HTML

### Open Redirect Surface (B — 90/100)

*2 link(s) carry redirect-shaped query parameter(s)*

- **[INFO]** 2 link(s) carry redirect-shaped query parameter(s) — Heuristic flag -- whether each endpoint actually permits an arbitrary redirect target depends on server-side validation. Audit the listed paths' redirect-target handling: the endpoint should either (a) restrict to a relative path, (b) restrict to an allowlisted host set, or (c) sign the target. Open redirects power phishing flows (the attacker's URL begins with your trusted domain) and bypass some SSRF-mitigation cookie scoping. Common parameter names flagged: redirect, redirect_uri, redirect_url, redirecturl, return, returnto, return_to, returnurl, return_url, next, nexturl, next_url, continue, goto, dest, destination, forward, target.

### Auth Security (A+ — 100/100)

*Page is not a login form -- auth-security checks are N/A*

- **[PASS]** Page does not appear to be a login form

### Subdomain Inventory Exposure (A+ — 100/100)

*No risky subdomain names in certificate SANs*

- **[PASS]** No risky subdomain names in certificate SANs

### JS Library Vulnerabilities (A+ — 100/100)

*No known vulnerabilities*

- **[PASS]** No known JavaScript library vulnerabilities detected

### Information Leakage (A+ — 100/100)

*No exposures*

- **[PASS]** security.txt is present — good practice
- **[PASS]** No sensitive files exposed

### Email Security (B — 72/100)

*DMARC: quarantine, SPF: ~all, DKIM*

- **[PASS]** DMARC policy is quarantine — good protection
- **[INFO]** SPF ends in ~all (soft fail) — Soft fail tells receivers to accept-but-mark unauthorized mail. Migrate to -all once you've confirmed all legitimate senders are listed (DMARC aggregate reports help verify).
- **[PASS]** DKIM configured (selectors: smtpapi, google, selector1, s1, k1, s2, k2)
- **[INFO]** MTA-STS not configured — MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts.<domain> and a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt.
- **[INFO]** TLS-RPT not configured — TLS-RPT (RFC 8460) lets MTAs report TLS-handshake failures, so you can detect and fix MTA-STS misconfigurations. Add a TXT record at _smtp._tls.<domain>.
- **[INFO]** BIMI not configured — BIMI (Brand Indicators for Message Identification) lets supporting clients (Gmail, Apple Mail, Yahoo) display your verified logo next to your messages. Optional but raises trust signals. Requires DMARC at p=quarantine or p=reject to be honored.

### API Surface (A+ — 100/100)

*No API specs or GraphQL introspection found (probed 11 candidate path(s))*

- **[PASS]** No API specs or GraphQL introspection found (probed 11 path(s))

### Permissions-Policy (D — 40/100)

*No header set*

- **[WARNING]** No Permissions-Policy header — Consider adding a Permissions-Policy header to restrict browser feature access from embedded content.

### CORS Configuration (B — 80/100)

*No CORS headers*

- **[PASS]** No CORS headers present — secure default

## Performance

### Page Weight Budget (C — 59/100)

*1.9 MB transferred, 168 requests*

- **[INFO]** Page weighs 7.5 MB (1.9 MB transferred)
- **[WARNING]** JavaScript is 1.3 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[INFO]** CSS is 286 KB — consider purging unused styles — Remove unused CSS rules with tools like PurgeCSS to reduce stylesheet size.
- **[WARNING]** 168 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 0.40 g CO2 per page load

### Third-Party Impact (D — 50/100)

*93% third-party, 0 ms blocking*

- **[WARNING]** Third-party code accounts for 93% of page weight (1.8 MiB of 1.9 MiB)
- **[PASS]** Third-party blocking time is low (0 ms)

### Text Compression (A+ — 100/100)

*All text resources are compressed*

- **[PASS]** All text resources are compressed

### Image Optimization (C — 60/100)

*22 images, 0 KB saveable*

- **[WARNING]** https://camo.githubusercontent.com/604e3db9c875111... is missing width/height — may cause layout shift — Set explicit width and height to prevent CLS.

### JS Execution Cost (F — 20/100)

*4060ms total JS execution*

- **[WARNING]** Unattributable: 1058ms CPU time
- **[WARNING]** https://github.githubassets.com/assets/react-lib-1...: 946ms CPU time
- **[WARNING]** https://github.com/007revad/Synology_Docker_Export: 893ms CPU time
- **[WARNING]** https://github.githubassets.com/assets/catalyst-fe...: 598ms CPU time
- **[INFO]** https://github.githubassets.com/assets/98944-e7414...: 155ms CPU time
- **[WARNING]** Third-party scripts: 2110ms (52% of total)

### Font Loading (A+ — 100/100)

*No web fonts (system fonts)*

- **[PASS]** No web fonts loaded — system fonts are fastest

### JS Bundles (D — 40/100)

*106 scripts, 333 KB unused*

- **[WARNING]** https://github.githubassets.com/assets/72373-26aef...: 124 KB unused (78%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/primer-reac...: 58 KB unused (43%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/react-core-...: 51 KB unused (64%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/behaviors-b...: 47 KB unused (81%) — Consider code splitting or tree shaking to reduce unused code.
- **[WARNING]** https://github.githubassets.com/assets/2850-0ab48f...: 27 KB unused (89%) — Consider code splitting or tree shaking to reduce unused code.
- **[INFO]** Total unused JavaScript: 333 KB

### Resource Caching (A+ — 100/100)

*All resources properly cached*

- **[PASS]** No caching issues found

### Critical Rendering Path (A+ — 100/100)

*No render-blocking resources*

- **[PASS]** No render-blocking resources detected

### Resource Hints (A — 90/100)

*6 hints, 0 missing preconnects*

- **[INFO]** 2 dns-prefetch redundant with preconnect on same origin — preconnect already does the DNS lookup; adding dns-prefetch to the same origin is at best a no-op. Sample: https://github.githubassets.com, https://avatars.githubusercontent.com. Remove the redundant dns-prefetch entries.
- **[INFO]** 2 URL(s) appear in multiple hints — The same href shouldn't appear in multiple hint rels -- one wins, the others are wasted markup and may confuse cache behavior. Sample: https://github.githubassets.com (dns-prefetch+preconnect), https://avatars.githubusercontent.com (dns-prefetch+preconnect).
- **[PASS]** Page uses 6 resource hint(s)

### HTTP/3 (QUIC) (B — 75/100)

*HTTP/3 not advertised*

- **[INFO]** HTTP/3 (QUIC) is not advertised — HTTP/3 isn't advertised via Alt-Svc and the worker didn't negotiate h3. HTTP/3 reduces handshake latency (1-RTT instead of 2-3 RTTs) and is more resilient on lossy connections. Most modern CDNs (Cloudflare, Fastly, AWS CloudFront, Google Cloud CDN) support HTTP/3 with a single config switch -- consider enabling for mobile-heavy workloads.

### Compression Algorithm (B — 80/100)

*Main response uses gzip; brotli would be ~20% smaller*

- **[INFO]** Main HTML response uses gzip (brotli would be ~20% smaller) — All current browsers support brotli. Most CDNs (Cloudflare, Fastly, AWS CloudFront, Vercel, Netlify) can switch from gzip to brotli with a single config flag. Origin servers (nginx, Apache) need a brotli module compiled in -- nginx-brotli or Apache mod_brotli.

### LCP Image Preload (A+ — 100/100)

*LCP preload audit not available*

- **[PASS]** LCP image preload audit not available for this scan

### Main HTML Cache-Control (A+ — 100/100)

*Main HTML max-age=0 (≤ 5min) is appropriate*

- **[PASS]** Main HTML max-age=0 (≤ 5min) is appropriate

### Server-Timing Observability (B — 85/100)

*No Server-Timing header found*

- **[INFO]** No Server-Timing header found — Server-Timing exposes backend timing breakdowns to browser DevTools (e.g., `db: 45ms; render: 120ms; cache: 2ms`). Useful for diagnosing slow pages without backend log access. Most modern frameworks (Next.js, Cloudflare Workers, Fastly) emit it automatically; absence on a managed platform usually means telemetry headers are stripped at the edge.

### Server Response Intelligence (A+ — 100/100)

*2 server-response signal(s) detected*

- **[PASS]** `Vary` header declared: X-PJAX, X-PJAX-Container, Turbo-Visit, Turbo-Frame, X-Requested-With, X-GitHub-C... — The page declares a `Vary` header, telling downstream caches which request headers the response varies on. Critical for content-negotiated responses (compression, language, cookies, device class).
- **[PASS]** `ETag` present -- conditional GET supported

### Page Weight Inventory (D — 40/100)

*168 resources · 1.9 MB · 333 KB savings available*

- **[WARNING]** Page weight 1.9 MB exceeds 1 MB target by 923 KB
- **[INFO]** ~333 KB of savings available
- **[WARNING]** 150 third-party resources (93% of weight)

### Render-Blocking Resources (A+ — 100/100)

*No render-blocking resources detected*

- **[PASS]** No render-blocking resources detected in <head>

### Third-Party Resources (A+ — 100/100)

*No third-party resources detected*


### JavaScript Blocking (A — 90/100)

*1 JS blocking issue(s) detected*

- **[WARNING]** Total JS execution time is 4.1 s -- over the 3.5s budget — Total JavaScript execution (parse + compile + run) across all scripts exceeds 3.5 seconds. On low-end devices that becomes 7-15+ seconds and shows up directly in TBT and INP. Reduce by: tree-shaking unused dependencies, code-splitting (dynamic `import()`), removing or deferring third-party tracking, and replacing heavy frameworks where they're not needed.

### CSS Performance Depth (A — 88/100)

*1 CSS depth issue(s) detected*

- **[WARNING]** 25 render-blocking stylesheet(s) -- recommended: <=3 — Each `<link rel="stylesheet">` without a non-blocking `media` attribute holds up the first paint. Browsers download all of them before painting any content. Consolidate into 1-2 critical-path stylesheets; defer non-critical CSS via `<link rel="stylesheet" media="print" onload="this.media='all'">` or via the loadCSS pattern; inline above-the-fold CSS in `<style>` to short-circuit the request entirely.

## Content Quality

### Links (B — 83/100)

*200 links checked, 196 healthy, 3 broken*

- **[WARNING]** 196 of 200 links are healthy
- **[WARNING]** Broken link: https://github.githubassets.com — Found in <link href>. Returns HTTP 404.
- **[WARNING]** Broken link: https://github.githubassets.com/ — Found in <link href>. Returns HTTP 404.
- **[INFO]** Long redirect chain: https://maintainers.github.com (3 hops)
- **[CRITICAL]** Broken link: https://github.com/signup?ref_cta=Sign+up&ref_loc=header+... — Found in <a href>. Returns HTTP 403.

### Mixed Content (A+ — 100/100)

*No mixed content detected — all resources use HTTPS.*

- **[PASS]** No mixed content detected — all resources use HTTPS

### Open Graph (A — 90/100)

*Open Graph tags are well configured for social sharing.*

- **[CRITICAL]** og:image is not reachable — The og:image URL could not be fetched. Social platforms won't be able to display it.
- **[INFO]** og:title is long (120 characters) — Titles over 60 characters may be truncated in social sharing previews.

### Open Graph / Twitter Card Depth (A+ — 100/100)

*OG image dimensions and Twitter card configuration look healthy*

- **[PASS]** OG/Twitter Card depth is clean -- dimensions, card type, and inheritance all valid

### Structured Data (C — 40/100)

*No structured data (JSON-LD) found.*

- **[INFO]** No structured data (JSON-LD) found — Adding structured data helps search engines understand your content and can enable rich results.

### Rich Results Eligibility (C — 75/100)

*No JSON-LD found -- no rich-result eligibility*

- **[INFO]** No JSON-LD structured data on the page — No `<script type="application/ld+json">` blocks found. Without structured data, search engines fall back to inferring page meaning from raw HTML -- which works but doesn't unlock SERP features (rich snippets, knowledge panel, FAQ accordion, breadcrumb trail). Adding even basic JSON-LD (Organization for the site identity, BreadcrumbList for navigation context) is a low-effort SEO win.

### Image Optimization (F — 30/100)

*6 issues found across 17 images*

- **[WARNING]** 2 images significantly larger than display size — Resizing to display dimensions could save approximately 2 KB.
- **[WARNING]** 11 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 16 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** All 7 images use legacy formats (JPEG/PNG/GIF) — WebP offers 25-35% smaller files than JPEG. Use <picture> with <source type="image/webp"> for modern format support.
- **[WARNING]** 8 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
- **[INFO]** 6 image(s) wider than 400px without srcset (no responsive serving) — These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://github.com/007revad/Synology_Docker_Export/raw/main/images/script.png, https://github.com/007revad/Synology_Docker_Export/raw/main/images/v104.png, https://github.com/007revad/Synology_Docker_Export/raw/main/images/exports.png (+3 more).

- **[INFO]** No CAA iodef tag — won't be notified of failed issuance attempts — Add `0 iodef "mailto:security@example.com"` to receive notifications when a CA refuses issuance because it doesn't match your CAA policy. Useful signal for detecting issuance attempts by unauthorized CAs.

### Reverse DNS (B — 75/100)

*0/1 IPs match cert SAN*

- **[INFO]** PTR for 140.82.121.3 does not match any cert SAN: lb-140-82-121-3-fra.github.com — Common when behind a CDN or shared hosting (PTR points at the provider's hostname). Mismatch can also affect mail deliverability if this IP sends email -- many MTAs reject mail when forward+reverse DNS disagree.

### Multi-Resolver DNS Speed (A+ — 100/100)

*Mean 15ms across 3 resolvers (spread 29ms)*

- **[PASS]** Quad9: 0ms

### URL Variants (A — 90/100)

*www/non-www, trailing slash, HTTP→HTTPS*

- **[PASS]** www/non-www redirect configured correctly (preferred: non-www)
- **[WARNING]** Trailing slash inconsistency — both versions serve content
- **[PASS]** HTTP correctly 301-redirects to HTTPS

### Domain Intelligence (A — 90/100)

*github.com — via MarkMonitor Inc., 19 years, 1 months old, hosted on GitHub Pages*

- **[WARNING]** Domain expires in 52 days — Consider enabling auto-renewal to prevent accidental expiration.
- **[INFO]** DNSSEC is not enabled — DNSSEC protects against DNS spoofing attacks. While not required, enabling DNSSEC adds an additional layer of security. Contact your DNS provider to enable it.
- **[PASS]** Registrar: MarkMonitor Inc.
- **[WARNING]** Registrar lock is NOT enabled — The domain can be transferred without an unlock step. Enable registrar lock (clientTransferProhibited) in your registrar's control panel to protect against unauthorized or accidental transfers.

## Availability

### CDN & Delivery (D — 50/100)

*No CDN detected*

- **[WARNING]** No CDN detected — A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

### HTTP Caching (B — 75/100)

*max-age=0, private, must-revalidate*

- **[PASS]** Cache-Control header is set
- **[PASS]** ETag present — enables conditional (304) responses

### Operational Status Page (A+ — 100/100)

- **[PASS]** Public health endpoint at https://github.com/health

### CDN Cache Observability (B — 85/100)

*No CDN cache-status headers in the response*

- **[INFO]** No CDN cache-status headers in the response — Without an X-Cache / CF-Cache-Status / X-Vercel-Cache / Age header, you can't tell from outside whether a request hit the cache or went to origin. Operationally important: enables debugging stale-content reports and verifying cache rules. Most managed CDN platforms emit at least one of these by default; absence often means the platform's diagnostic headers are stripped at an upstream proxy.

## Accessibility

### Landmark Structure (A — 90/100)

*8 landmarks*

- **[PASS]** <main> landmark present
- **[PASS]** 4 <nav> landmark(s) found
- **[PASS]** All <nav> elements are properly labeled
- **[PASS]** Skip navigation link present
- **[WARNING]** Skip link target(s) don't exist on page: #start-of-content — The skip-link anchor (e.g., `href="#main"`) points at an ID that has no corresponding element on the page.

### Heading Hierarchy (C — 60/100)

*29 headings, 2 skip(s)*

- **[WARNING]** Multiple H1 headings (2 found) — A page should have only one H1. Multiple H1s dilute the document outline.

- **[PASS]** No iframes on this page

### Tap Target Adequacy (C — 75/100)

*9 tap target(s) too small or too close together*

- **[WARNING]** 9 tap target(s) too small or too close to neighbors — WCAG 2.5.5 (Level AAA) requires interactive targets to be at least 44x44 CSS pixels; WCAG 2.5.8 (Level AA, added in 2.2) requires 24x24 minimum. Failing targets cause mis-taps for users with motor impairments, large fingers, or shaky hands -- and are a major bounce-rate driver on mobile commerce flows. Lighthouse measures rendered rects + adjacent-element spacing; the failing list is in the Lighthouse 'tap-targets' audit detail panel.

### Mobile-Readable Font Sizes (A+ — 100/100)

*All 148 visible text node(s) render at >= 12 CSS pixels*

- **[PASS]** 512x512 icon present
- **[PASS]** Display mode: standalone

### PWA Depth (A — 90/100)

*2 PWA signal(s) surfaced*

- **[INFO]** Manifest has no maskable icon — Android 12+ Adaptive Icons crop non-maskable icons to a circle or squircle -- frequently hiding important parts of the logo. Add at least one icon entry with `"purpose": "maskable"` (or `"any maskable"`) and a maskable-aware design (16% safe-zone padding around the inner mark).
- **[INFO]** Manifest is missing `theme_color` — Without `theme_color`, the install prompt and Android status bar fall back to a generic tint instead of your brand color. Add a hex color (e.g. `"theme_color": "#0066cc"`); for richer support, mirror it via `<meta name="theme-color" content="#0066cc">` so non-installed browsers also pick it up.

### Dark Mode Support (B — 80/100)

*Dark mode detected*

- **[PASS]** color-scheme meta tag present — The site declares support for light and dark color schemes via <meta name='color-scheme'>.
- **[INFO]** Theme-color present but no dark variant — A theme-color is set but no dark-specific variant was found. The browser toolbar may not adapt for dark mode users.
- **[INFO]** Detection limited to meta tags and inline styles — External CSS files may contain prefers-color-scheme rules not visible to this scan.

### Print Stylesheet (D — 40/100)

*No print styles*

- **[INFO]** No print-specific styles detected — When users print this page, they get the screen layout including navigation and non-essential elements. Add @media print rules to hide navigation and optimize layout for paper.

### Navigation UX (F — 35/100)

*1 navigation pattern(s)*

- **[PASS]** Skip navigation link detected
- **[PASS]** 4 navigation landmark(s) detected
- **[PASS]** Hamburger menu detected (responsive design)

### Mobile UX Depth (A+ — 100/100)

*2 mobile-depth signal(s) detected*

- **[PASS]** iOS smart-banner opt-in present (`apple-itunes-app`) — The page declares a companion iOS app via `<meta name="apple-itunes-app" content="app-id=...">`. iOS Safari shows a smart banner offering to open the page in the app, with an unobtrusive 'X' to dismiss. Recommended when you have a published companion app.
- **[PASS]** Browser-chrome `theme-color` meta tag present — The page sets `<meta name="theme-color" content="...">`, which Android Chrome uses to tint the status bar and iOS Safari uses for the toolbar background. Brand polish that costs nothing and Just Works.

## SEO

### Canonical URL (B — 80/100)

- **[INFO]** Title uses 4 different separator characters: -, /, :, · — The page title `GitHub - 007revad/Synology_Docker_Export: Export Synology Co...` uses multiple separator characters (-, /, :, ·). Consistent separator use is a soft signal of careful editorial control; mixed separators usually mean the title was assembled from multiple template fragments (CMS title + brand + section) without a normalization step. Pick one separator (commonly `|`, `-`, or `:`) and stick with it across the whole site.

### Content Depth (C — 65/100)

*798 words, Very Difficult*

- **[PASS]** Page has 798 words of content
- **[INFO]** Text-to-HTML ratio is 2% — Very low ratio suggests heavy framework overhead or boilerplate.

- **[INFO]** No sitemap.xml found — Sitemaps help search engines discover and prioritize URLs. Not strictly required for small sites where every page is linked from the homepage, but recommended once a site grows beyond a few dozen URLs.

### Sitemap × Robots Consistency (C — 75/100)

*Sitemap or robots.txt missing -- consistency check skipped*

- **[INFO]** Cross-check skipped (sitemap or robots.txt absent)

### Sitemap Hygiene (A+ — 100/100)

*No sitemap to evaluate -- depth check is N/A*

- **[PASS]** No sitemap fetched -- depth check skipped

### Markup Quality (A+ — 95/100)

*1 markup-quality issue(s) detected*

- **[INFO]** 1 redundant ARIA role attribute(s) on native semantic element(s) — The W3C "ARIA in HTML" spec calls this its first rule: don't use ARIA when a native HTML element already conveys the semantics. `<button role="button">`, `<a href role="link">`, `<nav role="navigation">`, `<main role="main">` -- the role attribute either does nothing or shadows the native semantic, occasionally breaking assistive-tech behaviors. Remove the redundant role.

## Sustainability

### CO2 Per Page Load (B — 70/100)

*0.54g CO2 per view*

- **[INFO]** 0.54g CO2 per page view — This page transfers 1.9 MB, producing an estimated 0.54g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.10g, network 0.09g, end-user device 0.35g.
- **[INFO]** At 10,000 monthly views: 64.6 kg CO2/year — With 10,000 page views per month, this page would generate approximately 64.6 kg of CO2 annually — equivalent to charging 8075 smartphones.

### Green Hosting (D — 40/100)

*Not green*

- **[INFO]** No confirmed renewable energy commitment detected — Consider providers like Cloudflare, Google Cloud, or Vercel that match 100% of their energy use with renewables.
- **[INFO]** Green hosting status based on known provider commitments — Green hosting detection uses a curated database of provider renewable energy commitments. This is not a real-time verification. For authoritative checks, visit thegreenwebfoundation.org.

### Repeat Visit Weight (A+ — 100/100)

*98% cached*

- **[PASS]** 98% reduction on repeat visits — Returning visitors download only 48 KB (vs 1946 KB first visit). 167 of 168 resources are served from browser cache, saving 0.53g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.01g CO2 (first visit: 0.54g)

### Carbon Budget (B — 70/100)

*43th percentile*

- **[INFO]** 0.54g CO2 — below the median website (0.60g) — Better than an estimated 57% of websites, but above the sustainability target of 0.50g. Reducing page weight would help reach the target.
- **[INFO]** Estimated 43th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (B — 80/100)

*83% efficient*

- **[INFO]** Transfer efficiency: 83% — An estimated 332 KB (17%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 332 KB of unused JavaScript. This wasted data produces 0.09g of unnecessary CO2 per page view.

### Web Font Weight Variants (B — 90/100)

*No detectable Google Fonts weights*

- **[INFO]** No detectable Google Fonts weights — The analyzer detects font weights via Google Fonts URL parameters (~70% of font-using sites). Self-hosted fonts and non-Google CDN fonts aren't visible to URL-based detection. If you self-host fonts, manually audit how many @font-face weights you ship -- 2-3 weights per family is typically enough; 5+ is usually unused payload.
