- **[WARNING]** Cookie 'sp-cdn' has no SameSite attribute — Without an explicit SameSite attribute, browser default behavior varies. Set SameSite=Lax or Strict.

### Cookie Hygiene (A+ — 100/100)

*All 6 cookie(s) pass hygiene checks*

- **[PASS]** All 6 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 — 85/100)

*Vulnerability disclosure policy*

- **[PASS]** security.txt found
- **[WARNING]** security.txt: Missing required 'Expires' field (RFC 9116)

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

*All 6 new-tab link(s) carry rel=noopener*

- **[PASS]** All 6 new-tab link(s) carry rel=noopener

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

*91 inline style attribute(s) detected*

- **[WARNING]** 91 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. 91 inline style(s) is high. Affected element types include: img, label, select, a, span. 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 (0/26 third-party resources)*

- **[WARNING]** SRI adoption: 0/26 third-party resources protected (0%) — Of 26 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://images-na.ssl-images-amazon.com/images/I/215h87l68bL.js
  - https://m.media-amazon.com/images/I/214aTrUk8lL._RC|51nfWTBkewL.css_.css?AUIClients/AmazonUI

  - https://m.media-amazon.com/images/I/61xJcNKKLXL.js?AUIClients/AmazonUIjQuery
  - https://m.media-amazon.com/images/I/413itl3RijL.js?AUIClients/PRIVCONAssets-centralized-prompting

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 (F — 35/100)

*0% high-risk feature coverage (0/10)*

- **[WARNING]** Permissions-Policy covers 0/10 high-risk features (0%) — The Permissions-Policy header explicitly declares policies for 0/10 high-risk features.

Covered: 

Not declared (default-allow): camera, microphone, geolocation, payment, usb, serial, midi, accelerometer, gyroscope, magnetometer

The non-declared features fall back to their spec-default policy (usually `self`), which means an XSS-injected or compromised iframe could request them. For features the page genuinely doesn't use, declare `feature=()` to fully close them.

### Referrer-Policy Strictness (B — 75/100)

*Referrer-Policy header not set -- browser default applies (modern: strict-origin-when-cross-origin; legacy browsers: no-referrer-when-downgrade)*

- **[INFO]** Referrer-Policy header not set -- browser default applies — Without an explicit `Referrer-Policy` header, the browser falls back to its default policy. Modern browsers (Chrome 85+, Firefox 87+, Safari 15+) default to `strict-origin-when-cross-origin`, which is privacy-safe. Legacy browsers default to the leaky `no-referrer-when-downgrade`, which sends the full URL (including path + query) on cross-origin HTTPS-to-HTTPS requests. Set an explicit header to ensure consistent behavior:

```
Referrer-Policy: strict-origin-when-cross-origin
```

This matches the modern browser default and is privacy-safe without breaking referrer-based same-origin analytics.

### 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 (A+ — 100/100)

*No redirect-shaped query parameters in DOM links*

- **[PASS]** No redirect-shaped query parameters in DOM links

### 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

- **[PASS]** HTTP/3 (QUIC) is supported — First-load mobile users on cellular networks see meaningful latency improvements with HTTP/3. The QUIC transport collapses TLS + TCP handshakes into one and recovers faster from packet loss.

### 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 uses no-cache -- safe revalidate-on-request policy*

- **[PASS]** Main HTML uses no-cache -- safe revalidate-on-request policy

### 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+ — 95/100)

*2 server-response signal(s) detected*

- **[PASS]** `Vary` header declared: Accept-Encoding,User-Agent — 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).
- **[INFO]** No `ETag` or `Last-Modified` -- conditional GET not supported — Without either header, browsers can't issue conditional GETs and refresh always re-downloads the full response body even when nothing changed. Add `ETag: "<hash>"` (or `Last-Modified: <date>`) on cacheable responses; the server returns 304 Not Modified when the client's cached copy is still valid, saving bandwidth.

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

*145 resources · 10.6 MB · 283 KB savings available*

- **[WARNING]** Page weight 10.6 MB exceeds 1 MB target by 9.6 MB
- **[INFO]** ~283 KB of savings available
- **[WARNING]** 134 third-party resources (96% of weight)
- **[INFO]** 2 resources over 200KB

### 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 (B — 84/100)

*2 JS blocking issue(s) detected*

- **[WARNING]** 1 render-blocking <script src> tag(s) without async/defer — Each `<script src=...>` without `async`, `defer`, or `type="module"` blocks HTML parsing while the browser fetches and executes it. The block lasts the entire round-trip + execution time -- on slow networks this translates directly into LCP delay. Add `defer` (executes after parse, in source order) for scripts that interact with the DOM, or `async` (executes whenever ready) for analytics / independent scripts. Module scripts (`type="module"`) are deferred by default.
- **[WARNING]** Total JS execution time is 10.2 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 (B — 78/100)

*2 CSS depth issue(s) detected*

- **[WARNING]** 10 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.
- **[WARNING]** 1 `@font-face` rule(s) without `font-display` -- causes FOIT — An `@font-face` rule without `font-display` causes Flash of Invisible Text (FOIT): the browser hides the styled text for up to 3 seconds while the custom font downloads, then either swaps to fallback (Chrome / Firefox) or stays invisible (older Safari). Add `font-display: swap` (shows fallback immediately, swaps in the custom font when ready) or `font-display: optional` (uses fallback if the font isn't ready in 100ms; never causes visible swap). Either eliminates FOIT outright.

## Content Quality

### Links (A+ — 100/100)

*200 links checked, 200 healthy, 0 broken*

- **[PASS]** 200 of 200 links are healthy

### Mixed Content (A+ — 100/100)

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

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

### Open Graph (F — 50/100)

*Open Graph tags need attention — social sharing previews may be incomplete.*

- **[WARNING]** Missing og:title — The og:title tag controls the title shown in social sharing previews.
- **[WARNING]** Missing og:image — The og:image tag provides a preview image for social sharing.
- **[INFO]** Missing og:url — The og:url tag specifies the canonical URL for the shared content.
- **[INFO]** Missing og:type — The og:type tag helps social platforms categorize the content.
- **[INFO]** Missing og:site_name — The og:site_name tag displays the website name in social previews.
- **[INFO]** Missing twitter:card — Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

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

*No OG image or Twitter card set -- depth check is N/A (presence covered by Open Graph section)*

- **[PASS]** No OG image / Twitter card to evaluate

### 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 — 25/100)

*7 issues found across 74 images*

- **[WARNING]** 60 images missing explicit width/height — Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
- **[INFO]** 64 below-fold images missing loading="lazy" — Lazy loading defers below-fold images, reducing initial page weight.
- **[WARNING]** All 73 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]** 1 images missing alt text — Alt text is essential for screen readers and SEO. Every meaningful image needs descriptive alt text.
- **[WARNING]** Total image weight: 1037 KB (1.0 MB) — Consider compressing images, using modern formats, and serving appropriately sized images.
- **[INFO]** 4 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://m.media-amazon.com/images/I/71KFcs8wmLL._SX3000_.jpg, https://m.media-amazon.com/images/I/61CV90xH8GL._SX3000_.jpg, https://m.media-amazon.com/images/I/71N5Uf0o2zL._SX3000_.jpg (+1 more).
- **[INFO]** 4 image(s) rendered at a different aspect ratio than the source — The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop). Sample: https://m.media-amazon.com/images/I/61ziT44eiDL._AC_SY170_.jpg, https://m.media-amazon.com/images/I/61vFp1PIj8L._AC_SY170_.jpg, https://m.media-amazon.com/images/I/81U2sRlmzNL._AC_SY170_.jpg (+1 more).

### Autoplay Media (A+ — 100/100)

## Infrastructure

### DNS Records (B — 75/100)

*1 A records, 39 ms lookup*

- **[PASS]** Resolves to 1 IPv4 address(es)
- **[INFO]** Single A record — no DNS redundancy — Multiple A records provide failover if one server goes down.
- **[PASS]** Has 5 IPv6 (AAAA) record(s)
- **[WARNING]** CNAME record at zone apex — A CNAME at the zone apex can break MX and NS records. Use ALIAS/ANAME or A records instead.
- **[INFO]** No NS records found
- **[INFO]** No MX records — email not configured via DNS
- **[INFO]** No SPF record found in TXT records — SPF helps prevent email spoofing. Add a TXT record starting with 'v=spf1'.
- **[PASS]** DNS resolution time: 39 ms

### Subdomain Takeover (A+ — 100/100)

*No subdomain takeover risk detected*

- **[PASS]** CNAME does not point at a known takeover-able service

### DNSSEC (B — 80/100)

*Unsigned (DNSSEC not deployed)*

- **[INFO]** DNSSEC is not deployed — The zone is not DNSSEC-signed. Users on validating resolvers (Cloudflare 1.1.1.1, Quad9 9.9.9.9, growing default in mobile resolvers) get no protection against DNS spoofing for this domain. Most registrars now offer DNSSEC at a single click; consider enabling it for sites where authenticity matters (banking, healthcare, government).

### CAA Records (B — 80/100)

*No CAA records (any CA may issue certificates)*

- **[INFO]** No CAA records published — Without CAA records, any publicly-trusted CA can issue certificates for this domain. Adding a CAA record (`yourdomain. IN CAA 0 issue "letsencrypt.org"`) restricts issuance to CAs you authorize. Required by CAB Forum baseline since 2017; the default of 'any CA' is widely supported but is the broader attack surface for issuance fraud.

### Reverse DNS (B — 75/100)

*0/6 IPs match cert SAN*

- **[INFO]** PTR for 18.164.122.31 does not match any cert SAN: server-18-164-122-31.jfk50.r.cloudfront.net — 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.
- **[INFO]** PTR for 2600:141b:1c00:d85::3bd2 does not match any cert SAN: g2600-141b-1c00-0d85-0000-0000-0000-3bd2.deploy.static.akamaitechnologies.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.
- **[INFO]** PTR for 2600:141b:1c00:da2::3bd2 does not match any cert SAN: g2600-141b-1c00-0da2-0000-0000-0000-3bd2.deploy.static.akamaitechnologies.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.
- **[INFO]** PTR for 2600:141b:1c00:d82::3bd2 does not match any cert SAN: g2600-141b-1c00-0d82-0000-0000-0000-3bd2.deploy.static.akamaitechnologies.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.
- **[INFO]** PTR for 2600:141b:1c00:d83::3bd2 does not match any cert SAN: g2600-141b-1c00-0d83-0000-0000-0000-3bd2.deploy.static.akamaitechnologies.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.
- **[INFO]** PTR for 2600:141b:1c00:d81::3bd2 does not match any cert SAN: g2600-141b-1c00-0d81-0000-0000-0000-3bd2.deploy.static.akamaitechnologies.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.

- **[PASS]** robots.txt is present
- **[INFO]** No sitemap.xml found — A sitemap helps search engines discover and index your pages more efficiently.
- **[INFO]** robots.txt does not reference a sitemap — Add a 'Sitemap:' directive to robots.txt so search engines can discover your sitemap.

### URL Variants (A — 90/100)

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

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

### Domain Intelligence (A+ — 100/100)

*amazon.co.uk — via Amazon.com, Inc., 32 years, 2 months old, hosted on AWS*

- **[PASS]** Domain registered until Dec 5, 2026 (3 months remaining)
- **[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: Amazon.com, 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.

- **[INFO]** This is an automated check, not legal advice — BeaverCheck detects technical indicators of consent management. This does not constitute a legal compliance assessment. Consult a privacy professional for GDPR/CCPA compliance.

### Consent UX Depth (A+ — 100/100)

*No consent-UX depth issues detected*

- **[PASS]** No consent-UX depth issues detected

### Tracker Inventory (A+ — 100/100)

*No hreflang tags on this page*

- **[PASS]** No hreflang tags found (single-language site)

### Internationalization Extras (A+ — 100/100)

*1 i18n signal(s) detected*

- **[PASS]** Mixed-language content: 1 subtree language(s) declared (en) — The page has elements with `lang="X"` attributes that differ from the root `<html lang>`. Per WCAG 3.1.2 (Level AA), this is the correct way to mark language-of-parts: a screen reader switches pronunciation when entering a `lang="fr"` block on an English page. The catalog is informational -- presence of subtree lang attributes is a positive a11y signal.

### Readability & Typography (A+ — 100/100)

*Font sizes and tap targets checked*


### Viewport Configuration (F — 30/100)

*No viewport meta tag*

- **[CRITICAL]** No viewport meta tag found — Without a viewport meta tag, the page will not render correctly on mobile devices.

### Accessibility Statement (A — 85/100)

*Statement found, no conformance level*

- **[INFO]** Accessibility statement found but lacks WCAG conformance level — Mature accessibility statements declare a target conformance level (e.g., WCAG 2.1 AA). Without a stated level, users and reviewers cannot tell what the statement actually commits to.

### GDPR Article 13 Disclosures (F — 12/100)

*1 / 8 Art. 13 categories matched in homepage body*

- **[WARNING]** GDPR Article 13 disclosure coverage: 1 / 8 categories — Scanned the homepage body text AND the linked /privacy page for GDPR Article 13 disclosures. Matched 1 of 8 categories: Recipients of personal data.

- **[PASS]** No third-party trackers detected

### Cookie & Tracker Inventory (A+ — 95/100)

*6 cookies · 0 trackers · 0 pre-consent*

- **[INFO]** 6 cookie(s) could not be classified

### Tracking Pixel Inventory (B — 90/100)

*1 tracking pixel(s) on the page*

- **[INFO]** 1 tracking pixel(s) on the page (1 domain(s)) — Tracking pixels are 1x1 / 2x2 cross-origin <img> tags that fire a GET request when the browser renders them -- no JavaScript, no cookies needed. They're how trackers survive when users disable JS or block third-party cookies, and they bypass most ad-blocker rules that target script src. Each one needs explicit disclosure under GDPR Art 7 / CCPA / ePrivacy because the request itself transmits the page URL + IP + user-agent + referrer to the tracker. Audit each surfaced domain: is it disclosed in your privacy policy? Is it conditional on the cookie banner? Affected domains: fls-eu.amazon.co.uk.

### Browser Fingerprinting (A+ — 100/100)

*No browser-fingerprinting libraries detected*

Naturally-focusable elements (links, buttons, form controls) become unreachable for keyboard users. (Common false-positive: hidden honeypot fields. Verify the element is genuinely interactive before removing the tabindex.)

### Iframe Accessibility (A — 90/100)

*1/1 iframe(s) missing title; 0 placeholder(s)*

- **[WARNING]** <iframe> missing title attribute (src="about:blank") — WCAG 4.1.2: iframes need a title attribute so screen readers can announce what's embedded. Without one, the announcement is just "iframe" -- the user has no way to decide whether to enter or skip.

### Tap Target Adequacy (B — 90/100)

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

- **[INFO]** 2 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 (B — 90/100)

*92% of visible text renders at >= 12 CSS px (12 below threshold)*

- **[INFO]** 12 text node(s) render below 12 CSS pixels on mobile — Mobile browsers default the root font-size to 16 px; text below ~ 12 px (75% of root) is hard to read without zooming. WCAG 1.4.4 (Resize Text) requires the page to support 200% zoom without loss of functionality -- which most layouts handle, but small base text still costs readability and conversion. Audit which selectors set sizes below 12 px (often footers, fine print, table cells) and bump them to 14-16 px or use rem units that scale with user preferences. Examples: <span> 10.0px ("USD"); <span> 10.0px ("99"); <span> 10.0px ("USD"); <span> 10.0px ("62"); <span> 10.0px ("USD").

*No PWA depth issues detected*

- **[PASS]** No PWA depth issues detected

### Dark Mode Support (D — 40/100)

*No navigation patterns*

- **[PASS]** 2 navigation landmark(s) detected
- **[INFO]** No breadcrumbs, search, or skip link detected — These navigation aids help users orient themselves and find content efficiently, especially on large sites.

*1 mobile-depth signal(s) detected*

- **[INFO]** No `<meta name="theme-color">` -- browser chrome falls back to default — Without `theme-color`, Android Chrome's status bar and iOS Safari's toolbar fall back to a generic gray. Adding a single hex color in `<meta name="theme-color" content="#0066cc">` tints them to your brand color across all mobile browsers.

- **[PASS]** No hreflang tags found -- completeness check is N/A

### Sitemap Freshness (C — 75/100)

### Markup Quality (A — 87/100)

*2 markup-quality issue(s) detected*

- **[INFO]** `<meta charset>` declared at byte 1287 -- past the 1024-byte spec window — The HTML5 spec requires the encoding declaration to appear in the first 1024 bytes. Browsers that started parsing in a default encoding and discover the real charset later DISCARD parsing state and re-parse from the top -- a measurable hit to First Contentful Paint. Move the `<meta charset>` tag to be the first child of `<head>`.
- **[INFO]** 6 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 (F — 15/100)

*3.00g CO2 per view*

- **[CRITICAL]** 3.00g CO2 per page view — This page transfers 10.6 MB, producing an estimated 3.00g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.56g, network 0.52g, end-user device 1.93g.
- **[INFO]** At 10,000 monthly views: 360.4 kg CO2/year — With 10,000 page views per month, this page would generate approximately 360.4 kg of CO2 annually — equivalent to charging 45052 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]** AWS: Renewable energy varies by region; committed to 100% by 2025
- **[INFO]** AWS CloudFront: Renewable varies by edge location
- **[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)

*96% cached*

- **[PASS]** 96% reduction on repeat visits — Returning visitors download only 416 KB (vs 10860 KB first visit). 143 of 145 resources are served from browser cache, saving 2.89g CO2 per repeat visit.
- **[INFO]** Repeat visit: 0.12g CO2 (first visit: 3.00g)

### Carbon Budget (F — 15/100)

*95th percentile*

- **[WARNING]** 3.00g CO2 — above the median website (0.60g) — Heavier than an estimated 5% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 95th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (A+ — 100/100)

*97% efficient*

- **[PASS]** Transfer efficiency: 97% — Only 283 KB of potential savings identified. Your page is well-optimized for size.

### 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.
