Interactive Surface CSS v1.5.0

1.5.0 - 2026-07-20

Added

• Added public transition tuple tokens for interaction properties, duration, easing, and delay while retaining the established motion and easing fallback chains.
• Added rendered precedence coverage for combined hover, persistent, transient active, busy, loading, disabled, and focus-visible states.

Changed

• Made disabled, busy/loading, transient active, persistent, hover, and base feedback follow one deterministic precedence order.
• Kept :focus-visible as an orthogonal outline so keyboard focus remains visible without replacing the active interaction state.
• Made the public hover lift token resolve directly, without hidden host-specific compensation.

Fixed

• Removed the UI-host +1px hover adjustment that changed authored lift values when packages were combined.
• Removed the UI-specific transition override and cross-package !important repair from the standalone preset.
• Fixed persistent state feedback being replaced by hover and busy/loading feedback being replaced during a transient press.

Accessibility

• Preserved a visible focus ring across base, pressed, selected, current, busy, and loading states.
• Kept disabled feedback authoritative while retaining reduced-motion state meaning and forced-colors system affordances.

Documentation

• Documented the exact state precedence, transition tuple, legacy fallbacks, and optional UI Style Kit integration boundary across the README and wiki.
• Updated release-facing package, CDN, testing, publishing, and roadmap guidance for 1.5.0.

Testing

• Added static contracts for transition tokens, legacy entry points, and the absence of UI-specific offset and importance rules.
• Added exact computed-style assertions for transition tuples, transform composition, state precedence, focus-visible overlays, and native file selector behavior.
• Stabilized Playwright worker counts and exercised the package contract in Chromium, Firefox, and WebKit.
