Blocking
Primary Workflow CompleteThe requested core path works from its initial state through a truthful completion, recovery, or explicitly bounded endpoint.Semantic Keyboard PathNative semantics, programmatic names, logical focus order, and keyboard operation cover the complete core workflow.Visible and Unobscured FocusEvery keyboard-focusable element has a visible high-contrast indicator that sticky or modal UI does not hide.Contrast and Non-color CuesText, meaningful graphics, controls, focus, and states meet relevant contrast thresholds and do not depend on color alone.Responsive Without LossSupported widths and text zoom preserve content, controls, reading order, and recovery without clipping or incoherent overlap.Honest ContentPeople, data, customer evidence, metrics, integrations, awards, and product claims are source-backed or clearly labeled as samples.Recoverable ErrorsReal failure paths explain what happened, preserve useful input, and provide a clear retry, correction, undo, or escape route.Reduced Motion Remains FunctionalReduced-motion preference removes nonessential travel and autoplay while preserving state feedback and every user outcome.

Stable LayoutMedia, loading, validation, long labels, and async results reserve space and do not unexpectedly move controls or content.Readable Measure and WrapHeadings, body copy, metadata, and actions retain intentional line lengths without brittle hard breaks or accidental one-word columns.First Viewport FitA hero-led entry fits its header, identity, subject crop, orientation, proof, and primary action within one declared short-viewport budget.Container and Bleed SeparationViewport-wide backgrounds and media extend independently while text, controls, and repeated panels remain aligned to the shared content grid.Reference TransformationStudied references inform principles and craft without reproducing one source's recognizable shell, navigation, typography, and accent composition.Design-system CoherenceTypography, spacing, color, icons, shape, surfaces, and interaction states follow one deliberate foundation.Authentic Primary MediaPrimary imagery reveals the actual subject users need to inspect and includes correct crop, dimensions, loading, and alternative text.Verified Delivery ReportThe final report names executed checks, inspected viewports and states, material fixes, and any remaining limitations.
