Roadmap

Interactive Surface CSS 1.5.0 is a release candidate. The work in this branch focuses the package on a durable interaction-state contract without expanding into layout or theme ownership.

1.5.0 release candidate

• Preserve every existing 1.x import, selector, hook, token fallback, and complete or companion stylesheet entry point.
• Expose public transition property, duration, easing, and delay tokens from state-core.css.
• Remove implicit UI-host lift compensation and cross-package transition importance from the standalone preset.
• Enforce disabled, busy/loading, transient active, persistent, hover, and base precedence while keeping focus-visible orthogonal.
• Preserve state meaning under reduced motion, higher contrast, and forced colors.
• Compose interaction translate with consumer transform, scale, and rotate.
• Keep UI Style Kit optional and preserve standalone package behavior.
• Align generated artifacts, package metadata, README, wiki, changelog, and release assertions.
• Lock the package, audit, Chromium, and full-browser release gates.

Publication, tagging, and a GitHub Release remain separate approval-gated steps.

After 1.5.0

Potential follow-up work must be driven by demonstrated consumer need:

• add targeted visual-regression baselines if state combinations become difficult to review
• expand framework examples without shipping framework wrappers
• add migration notes only when token evolution requires them
• add state recipes for new semantic platform behavior when browsers expose stable primitives

Permanent guardrails

The package should remain:

• small and framework-agnostic
• compatible with plain HTML and existing design systems
• accessibility-forward
• token-driven
• independently useful
• complementary to ui-style-kit-css and layout-style-css
• focused on interaction states rather than page layout or application theming

The Interface Systems Lab remains the canonical proof of the three-library composition.
