Roadmap

Interactive Surface CSS 1.7.3 is the current release. This patch preserves consumer-owned positioned-control topology without expanding into layout, theme, tooltip, or runtime ownership.

1.7.3 release

• Preserve every existing 1.x import, selector, hook, token fallback, and complete or companion stylesheet entry point.
• Preserve the 1.7.0 semantic feedback hooks, tokens, precedence, and preference behavior.
• Keep the internal state layer anchored while allowing consumer absolute, fixed, and sticky positioning to win regardless of stylesheet order.
• Cover positioned icon controls, nested surfaces, bounded internal scrolling, and narrow document-overflow containment in real browsers.
• 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.

Completed history

• 1.6.0 added optional shared semantic fallbacks for standalone paint, control geometry, focus, and default motion.
• 1.7.0 added CSS-only semantic outcome feedback, complete precedence coverage, and composable interaction motion.

After 1.7.3

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

• decide whether tooltip feedback should be attribute-triggered, ARIA-owned, or companion-owned
• decide whether tooltip motion needs a dedicated reduced-motion static state
• decide which package owns tooltip geometry before adding any selector
• 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.
