Choose a semantic building block and its failure state.

Triggers an action without implying navigation and preserves the v0.0.2 tone, size, class, and visible-state contract.

Preserves the v0.0.2 Card API as a specialized grouped-content plane built on Surface styling rather than the default wrapper for every section.

Names a compact status or classification with visible text and supporting tone while preserving the v0.0.2 API.

Groups visible form guidance and preserves the v0.0.2 class/state contract without implementing validation or input behavior.

Centers content, applies safe logical inline gutters, and selects an evidence-backed maximum measure without preventing full-bleed composition.

Creates finite section-level block rhythm and an optional structural boundary without child-margin hacks.

Arranges related children in one block-axis flow using gap rather than child margins.

Wraps actions, metadata, and compact facts without turning them into decorative pills.

Arranges repeated peers with one intrinsic mode and a restrained set of explicit column modes.

Pairs a primary region with supporting context using evidence-backed ratios and a deliberate narrow-screen stack.

Creates a restrained visual plane from package surface, border, radius, and elevation tokens while leaving content semantics to the chosen element.

Marks a meaningful horizontal separation with border tokens and native semantics.

Keeps essential text available to assistive technology while removing it from the visual flow without a zoom clipping defect.

Applies evidence-backed display, heading, body, lead, caption, eyebrow, data, or mono presentation without choosing document semantics for the consumer.

Navigates to another document, route, fragment, or downloadable resource with a persistent non-color affordance.

Makes a bounded content group one accessible navigation target without nested interactive controls.

Defines a visible-label search field, accessible clear action, result-status region, no-results recovery, and error association without exporting filtering behavior.

Pairs a marker and visible state text using package status triads without replacing Badge or adding implicit live-region behavior.

Preserves approximate layout during a truthful loading context without implying that content is loaded, verified, or complete.

Explains why useful content is absent and provides an appropriate next action without an implicit alert.

Names a failure, preserves source or reference context, and exposes explicit recovery without blame or false certainty.

Styles native progress semantics and visible labels without adding runtime behavior or implying completion from motion.

Presents process order and current/completed/upcoming state without implying navigation or beginning a product pattern.

Styles details and summary for FAQ or simple disclosure while preserving native open/closed and keyboard behavior.

Defines activation, success, reset, failure, disabled, and announcement obligations while leaving clipboard access in gallery or consumer code.

Provides a landmark and ordered route trail with decorative separators and an unlinked current page.

Presents a value with optional visible-direction delta, source/time metadata, and context without a chart or unsupported KPI certainty.

Styles native table content, density, numeric alignment, optional sticky header, and honest overflow affordance without providing data-grid behavior.
