SPEC-105 §4: a single dimensions/motion.css + motion tokens that render each reveal character — covering all section runes from one stylesheet, with the transform-composition and global-hook rules that keep it from becoming per-rune work.
Tracking started Jun 15 — check back for trends.
dimensions/motion.css — per-character keyframes/transitions keyed on data-reveal × data-in-view, plus the stagger delay (calc(var(--rf-reveal-index) * var(--rf-reveal-stagger))).tokens/) — duration, easing, travel distance, scale start, stagger interval; theme retunes character (calm vs punchy) purely via tokens.[data-reveal][data-in-view]; stagger targets the engine's index marker ([data-stagger][data-in-view] [style*="--rf-reveal-index"]), never > *. No rune's own CSS file gains a motion block for the baseline.translate/scale properties, never the transform shorthand, so it composes with the ~48 Lumina files already using transform (hover-lifts, frame displacement, drawer/nav) instead of clobbering them.blur downgrade — documented (and theme-applied) fallback to fade; all other characters animate compositor-only properties. Reduced-motion handled by the existing global reset (WORK-352).__content/__media offset) is opt-in polish, demonstrated but not required.dimensions/motion.css + motion tokens define each character keyed on data-reveal × data-in-view; the theme owns duration/easing/distance/scale/stagger as tokens.[data-reveal][data-in-view], stagger on the --rf-reveal-index marker (not > *); no rune CSS file gains a baseline motion block.translate/scale properties, never the transform shorthand; verified against at least one hover-transform rune (card/cta) that it composes rather than clobbers.blur documents/applies a downgrade to fade; other characters animate compositor-only props; CSS coverage passes for the new selectors.data-reveal/data-stagger/--rf-reveal-index.packages/lumina/styles/dimensions/ (precedent: state.css), packages/lumina/tokens/ · reduced-motion reset WORK-352 (global.css).
