amvcp-anim-foundation

What problem does it solve?

It prevents motion bugs, accessibility failures, and visual glitches by standardizing how every animation in the amvcp plugin is authored, gated for reduced motion, and composed safely.

Core Features & Use Cases

• Motion token contract: establishes the --vc-motion-*, --vc-duration-*, and --vc-easing-* naming contract with safe fallbacks when tokens are absent.
• Reduced-motion substitute pattern: enforces meaning-preserving substitutes for informational animations and removal for decorative-only animations—never blanket animation: none.
• Animation correctness invariants: mandates animation-fill-mode: both to stop staggered-entry flashes and provides guidance for choosing safe animated properties (favoring transform and opacity).
• Atom stamping contract for selection/decisions: stamps commentable atoms with stable data-ve-id/data-ve-type plus decision mini-pill mounting via the shared runtime.
• Dynamic wiring APIs: documents and coordinates refresh(root) for re-scanning and revealNow(el) for forcing immediate reveals.
• Keyframe catalog + anti-patterns: provides the canonical keyframe set and a checklist of mistakes to avoid (including OT-08 authoring plan structure).

Quick Start

Trigger this skill while authoring or debugging amvcp animations for motion tokens, easing curves, reduced-motion behavior, and keyframe selection by asking for the “motion tokens” and “animation contract” guidance.
