Coverage complete

Coverage-complete report-mode audit. Fresh-profile section and article paths exposed a consent/CMP interception; this is reported as direct user-journey evidence rather than an audit blocker.

All 58 atomic check outcomes

Principle / checkStatusConfidenceEvidence or reason
respect-user-preferences
respects-color-scheme
issueshighThe dark-condition screenshot is pixel-identical in appearance to the default capture; computed html color-scheme is normal and the main surface remains white.
F001 medium: The site remains light when the user requests a dark color scheme.
respect-user-preferences
respects-reduced-motion
issueshighUnder prefers-reduced-motion: reduce, the probe found no matching CSS rules and still observed a running 1100 ms atmLoader-white animation.
F002 low: Reduced-motion preferences are not represented in the page styles.
respect-user-preferences
respects-contrast
passhighScreenshot under prefers-contrast: more remained legible and Lighthouse isolated contrast failures separately; controls/text did not disappear.
implement-natural-interactions
view-transitions
issueshighRendered CSS contains no view-transition usage; the article and section are ordinary document navigations.
F003 low: Navigation changes use abrupt document swaps rather than View Transitions.
implement-natural-interactions
scroll-driven-animations
not-applicablehighNo parallax, scrollytelling, reveal, or other scroll-linked animation was observed on the representative pages, so there is no implementation to judge.
implement-natural-interactions
physical-gestures
not-applicablehighThe audited news surfaces expose ordinary links and scrolling, not a custom pull/swipe/drag gesture that requires a platform-native implementation.
provide-guided-navigation
scroll-state-aware-chrome
issueshighDOM evidence shows a fixed 56 px header on a 10,342 px main feed, but no scroll-state query, scroll timeline, or progress treatment.
F004 low: The fixed header does not communicate scroll position or adapt as the long feed is traversed.
provide-guided-navigation
anchored-positioning
not-applicablehighNo tooltip, anchored popover, or edge-positioned menu was exposed in the representative public surfaces.
provide-guided-navigation
directs-attention
passhighVisible section headings, explicit “Celý článek” links, and a persistent global header orient users through the feed.
maximize-content-reduce-noise
no-intrusive-interruptions
issueshighThe 360x800 article screenshot contains only the Seznam consent plans and Agree/Subscribe actions; article content is absent from the viewport.
F006 high: Fresh article and section visits are replaced by a full-screen consent/subscription choice wall.
maximize-content-reduce-noise
semantic-dismissible-primitives
issueshighDOM/CSS evidence shows .ribbon-menu as a fixed custom element; the page has zero dialog, popover, or details elements.
F005 low: The global menu is a custom fixed overlay rather than a semantic popover/dialog.
maximize-content-reduce-noise
reduced-chrome
passhighOutside the large reserved ad region, the homepage uses a compact 56 px header and content-led card grid rather than persistent side chrome.
adapt-to-the-form-factor
responsive-no-horizontal-scroll
issueshighLayout measured scrollWidth 479 versus clientWidth 360 (119 px overflow); the mobile screenshot shows the lead headline rendered mostly off-screen to the right.
F007 critical: The homepage has severe horizontal overflow at 360 px, clipping the lead story text.
adapt-to-the-form-factor
component-level-responsiveness
passlowCard dimensions and typography adapt at desktop widths, but direct evidence of component behavior is limited; the distinct mobile failure is recorded under responsive reflow.
adapt-to-the-form-factor
input-modality-aware
issueshighThe focus probe found no outline on the search input/button and numerous links; the main menu target is only 32x32 px.
F008 medium: Many interactive elements have no visible focus indicator and some targets are below recommended size.
support-core-task-success
clear-purpose-and-primary-action
passhighTitle, Novinky branding, lead headline, topical sections, and search make the news-reading purpose and next actions explicit.
support-core-task-success
primary-flow-completion
issueshighDirect article navigation produced a full-screen three-plan consent/subscription surface instead of the requested report, creating a mandatory detour.
F009 high: The representative read-article journey cannot reach the article in a fresh session without first resolving the consent wall.
support-core-task-success
clear-system-state-and-recovery
passhighThe synthetic 404 clearly says the page was not found and provides a prominent return-to-Novinky action.
be-fast-and-stable
good-core-web-vitals
issueshighLighthouse measured LCP 7.3 s, FCP 4.6 s, TBT 250 ms, and performance 0.55; the independent trace measured LCP/FCP 3.52 s.
F010 high: Lab loading performance is outside the good range.
be-fast-and-stable
visual-stability
issueshighThe mobile section layout observer recorded CLS 0.168 from a single shift at about 4.5 s, above the good threshold.
F011 medium: The section path shifts substantially during loading.
be-fast-and-stable
efficient-main-thread
passhighIndependent trace recorded one 51.86 ms long task and only 1.86 ms total blocking time during its capture.
be-fast-and-stable
efficient-resource-delivery
issueshighHAR recorded 130 requests and 2,056,434 transferred bytes, including 865,678 script bytes; Lighthouse LCP was 7.3 s.
F012 medium: The homepage delivery is heavy for a news index and delays content.
be-fast-and-stable
trim-unused-and-duplicate-code
issueshighLighthouse estimated 317 KiB unused JavaScript and 14 KiB unused CSS.
F013 medium: Substantial unused JavaScript and CSS are shipped on initial load.
be-inclusive
names-roles-labels
issueshighLighthouse failed image-alt, link-name, frame-title and accessibility-tree audits; the probe counted 140 unnamed links and two untitled iframes.
F014 high: Many links/images and embedded frames lack accessible names.
be-inclusive
sufficient-contrast
issueshighLighthouse color-contrast audit failed on the homepage.
F015 medium: Some text and controls do not meet WCAG contrast minimums.
be-inclusive
structure-and-focus
issueshighLighthouse failed heading-order; the probe begins with H6 elements before H1 and found many focusable links/controls with outline none.
F016 high: Heading order and keyboard focus treatment are unreliable.
be-inclusive
legible-text
passhighVisible article-card headlines use large, high-contrast typography and are readable where not affected by the separately reported mobile overflow.
be-inclusive
zoom-reflow-targets-and-media
issueshighAt 360 px the page overflows by 119 px and clips the lead headline, so equivalent zoom/reflow use is not preserved.
F017 medium: The layout does not reflow cleanly at a narrow viewport.
follow-best-practices
no-console-errors
issueshighLighthouse failed errors-in-console; its run also logged a malformed source-map mapping warning for xgemius.min.js.map.
F018 medium: The page logs browser errors.
follow-best-practices
sound-document-and-assets
issueshighThe images primitive found 8 images without dimensions, 6 without srcset, one oversized image, and 22 without alt.
F019 medium: Image markup is inconsistent despite a valid doctype/charset.
follow-best-practices
browser-platform-hygiene
issueshighLighthouse failed deprecations, bf-cache, and inspector-issues audits, including one BFCache failure reason.
F020 medium: The page triggers deprecated API, BFCache, and DevTools inspector issues.
be-discoverable
title-and-description
passhighRaw HTTP metadata shows unique descriptive titles and descriptions for home, section, and article, all with status 200.
be-discoverable
crawlable-and-mobile-friendly
issueshighThe DOM probe counted 140 href links without text, aria-label, or an alt-bearing image; Lighthouse link-name failed.
F021 medium: A large number of crawlable links have no descriptive text.
be-discoverable
canonical-and-indexing-signals
passhighAll three representative URLs return 200 with self-canonicals; robots.txt allows general crawling and declares four sitemap indexes.
be-discoverable
structured-and-shareable-metadata
passhighThe article raw HTML includes two JSON-LD blocks and page DOM includes Open Graph/Twitter metadata matching visible titles.
be-private-and-secure
secure-transport-and-headers
issueshighHeaders show CSP permits unsafe-inline and unsafe-eval; all four observed first-party cookies use SameSite=None. HSTS and nosniff are present.
F022 medium: Transport is HTTPS, but CSP and cookie posture are weaker than necessary.
be-private-and-secure
data-minimisation-and-third-parties
issueshighTracker evidence recorded 25 origins, 24 third-party origins and Google Tag Manager; HAR recorded 130 requests and 2.06 MB.
F023 high: The homepage exposes a broad third-party and analytics footprint before a demonstrated user choice.
be-private-and-secure
in-context-permissions-and-modern-auth
not-applicablehighThe public news-reading scope requires neither a browser permission nor authentication; no permission prompt fired on load. Account authentication was not required for the representative core task.
be-private-and-secure
defensive-browser-policies
issueshighPermissions-Policy is absent and CSP allows unsafe-inline/unsafe-eval; HSTS, frame protection, nosniff and Referrer-Policy are present.
F024 medium: Browser-enforced defenses are incomplete.
be-resilient
progressive-enhancement
passhighHomepage discoverability found 83% rendered-word coverage in raw HTML with title, H1 and description present; raw article HTML also contains its H1 and metadata.
be-resilient
resilient-runtime-behaviour
issueshighThe section/article DOM capture redirected to cmp.seznam.cz and reported “Unable to load … scmp-cw.js”; requested content was not present.
F025 high: The consent runtime can fail and replace requested content with an error surface.
be-resilient
offline-and-installable
issueshighA standalone web app manifest is linked, but the homepage probe found no controlling service worker and the manifest has an empty name.
F026 low: Installability intent is incomplete.
be-resilient
network-and-http-failure-states
passhighThe 404 state is useful and actionable; the CMP script failure also explains the failure and links support, though its content replacement is reported separately.
be-internationalised
lang-dir-and-logical-properties
passhighThe document declares lang="cs" and an LTR reading direction appropriate to Czech content.
be-internationalised
locale-aware-data
not-applicablehighNovinky is a deliberately Czech-language national publication in this audited scope; no locale switch, currency input, or multi-locale data flow was offered.
be-internationalised
time-zone-correctness
not-applicablehighNo event scheduling, recurring interval, user-entered date/time, or cross-zone coordination flow exists in the representative news-reading scope.
be-trustworthy
no-dark-patterns
passhighThe consent surface describes Free with ads, untargeted paid, and ad-free choices with prices and a Detailed settings link; no confirmshaming wording was observed.
be-trustworthy
humane-error-handling
not-applicablehighThe only authored form is a single optional search field with no required-field or multi-step validation state to exercise.
be-trustworthy
trustworthy-input-assistance
issueshighDOM form evidence reports autocomplete="off" on the only text input.
F027 low: The search field explicitly disables autocomplete.
be-trustworthy
safe-commercial-and-account-flows
passhighThe observed subscription options display monthly prices and an ad-free trial commitment directly on the choice cards.
be-sustainable
optimised-assets
issueshighImage audit found 8 missing dimensions, 6 missing srcset, one oversized asset, and only 3 of 44 URLs recognized as modern formats.
F028 medium: Image delivery leaves avoidable responsive-image waste.
be-sustainable
no-wasteful-work
passhighThe trace observed only one marginal long task and the page contains no autoplay audio/video; waste from third parties is recorded in the separate budget check.
be-sustainable
third-party-and-media-budget
issueshighThe page transferred 2.06 MB across 130 requests, including 866 KB scripts, and contacted 24 third-party origins.
F029 high: Third-party scripts and network traffic are disproportionate to the initial text-news experience.
be-agent-ready
structured-agent-capabilities
not-applicablehighEmerging agent actions are not required for this read-only public news scope; raw HTML remains machine-readable, and absence of WebMCP is treated as an opportunity rather than a failure.
be-agent-ready
on-device-inference
not-applicablehighNo user task in the audited scope requires on-device inference; absence of built-in summarization is not penalized under this emerging contextual principle.
be-memory-efficient
no-leak-under-repeated-interaction
issuesmediumHeap summaries increased from 446,555 to 529,564 nodes (+18.6%) and 23.0 MB to 27.7 MB (+20.6%) after ten menu open/close cycles. Separate fresh-profile snapshots reduce confidence, so confirm with same-session baseline/target/final analysis.
F030 medium: Heap size grew materially after repeating the menu interaction ten times.
be-memory-efficient
bounded-footprint
issuesmediumBaseline heap summary contains 446,555 nodes, 1,995,444 edges and 23.0 MB self size before extended interaction.
F031 low: The initial homepage object population is large for a primarily textual index.
be-memory-efficient
no-detached-dom-or-unbounded-listeners
passhighNeither heap summary exposed Detached* constructors among its largest retained constructor groups after ten menu cycles; no direct detached-DOM signature was observed.
