Coverage complete

Coverage-complete audit of five representative public templates/flows. Editing, authenticated contribution, donation/payment, and media-playback flows were not covered because they require state, credentials, or cross-site commitment beyond this public audit.

Principle / checkStatusConfidenceEvidence or reason
respect-user-preferences
respects-color-scheme
issueshighThe screenshot captured with prefers-color-scheme: dark remains a white, light-themed page, despite the CSS feature probe finding color-scheme rules.
F001 medium: The default experience does not follow the system dark preference.
respect-user-preferences
respects-reduced-motion
passmediumevaluate under prefers-reduced-motion: reduce found zero active animations and zero nonzero control transitions
respect-user-preferences
respects-contrast
passmediumhigh-contrast screenshot remained readable with visible controls; CSS probe found prefers-contrast/forced-colors support
implement-natural-interactions
view-transitions
issuesmediumThe stylesheet probe found no view-transition usage across the representative article while navigation is a central repeated interaction.
F015 low: Article and route changes use abrupt full-document swaps without View Transitions.
implement-natural-interactions
scroll-driven-animations
passmediumstylesheet probe found no scroll-linked animation and the site uses native document scrolling, avoiding main-thread scroll animation work
implement-natural-interactions
physical-gestures
passmediumscreenshots and DOM show standard browser scrolling and controls with no custom swipe/pointer gesture surface on tested paths
provide-guided-navigation
scroll-state-aware-chrome
issuesmediumThe long article screenshot and stylesheet probe show persistent table-of-contents/chrome but no scroll-state container query or scroll progress treatment.
F016 low: Long-form navigation chrome does not visibly adapt to scroll state.
provide-guided-navigation
anchored-positioning
passmediumtested overlays are centered preference UI or fixed menus with no anchor-dependent tooltip placement requirement observed
provide-guided-navigation
directs-attention
passmediumarticle has a visible table of contents, headings, selected page tab, skip link, and clear link styling
maximize-content-reduce-noise
no-intrusive-interruptions
issueshighDesktop and mobile screenshots show a large prompt over the homepage/article before interaction. On mobile it occupies the bottom of an already scaled-down viewport.
F002 medium: A language-variant prompt obscures core content on first load.
maximize-content-reduce-noise
semantic-dismissible-primitives
issueshighThe prompt is visible in screenshots, while the article DOM probe reports 0 dialog elements and 0 popover elements.
F003 medium: The visible modal-like preference prompt is not exposed with a native dialog or popover primitive.
maximize-content-reduce-noise
reduced-chrome
passmediumarticle content remains the dominant central surface and optional side chrome can be hidden
adapt-to-the-form-factor
responsive-no-horizontal-scroll
issueshighThe DOM reports meta viewport width=1120. The 360x800 layout records clientWidth 1120 and visual scale 0.321, and mobile screenshots show tiny desktop columns rather than reflowed content.
F004 critical: The site forces a 1120 CSS-pixel desktop layout into a 360-pixel mobile viewport.
adapt-to-the-form-factor
component-level-responsiveness
issueshighThe DOM reports meta viewport width=1120. The 360x800 layout records clientWidth 1120 and visual scale 0.321, and mobile screenshots show tiny desktop columns rather than reflowed content.
F004 critical: The site forces a 1120 CSS-pixel desktop layout into a 360-pixel mobile viewport.
adapt-to-the-form-factor
input-modality-aware
issueshighLighthouse reports target-size failures. The focus probe found multiple visible buttons, links, and the search input with outline none and no compensating box shadow.
F005 high: Touch targets and focus presentation are inconsistent.

passmediumhomepage, article, search and login screenshots each expose a descriptive heading and clear next action

passmediumarticle reading, exact search redirect, empty search, and login entry were reachable without dead ends
support-core-task-success
clear-system-state-and-recovery

be-fast-and-stable
good-core-web-vitals
issueshighLighthouse performance is 0.58 with FCP 4.2s, LCP 8.8s, Speed Index 5.3s, and TBT 210ms. The separate desktop trace was healthier at LCP 1.68s and TBT 24.81ms, showing a form-factor/network sensitivity.

issueshighLighthouse estimates 165 KiB unused JavaScript and 94 KiB unused CSS on the representative article.
F008 medium: The article ships substantial unused JavaScript and CSS.

sufficient-contrast
passmediumLighthouse accessibility review did not fail color-contrast and the high-contrast screenshot remains legible
be-inclusive

passmediumnavigation, preference chrome, search, and recovery states rendered without cut-off desktop overlays or blank runtime states
