Two streams, split by what the animation touches:
STREAM A — decorative backgrounds → the pack tier
- arts/scene: a consolidated scene runtime ($scene) that owns, once, the
citizenship every ad-hoc background reinvented or skipped (frame loop,
off-view pause, DPR cap, mandatory reduced-motion, WebGL context
loss/restore, scene budget, teardown). SceneDom port (adom satisfies it),
webgl/webgl2/canvas2d drivers + a custom-pipeline extension (vertexShader +
draw + glContext.depth/dprCap) for real geometry (beam, particles, dither,
grid, eter, pixel-blast, hyperspeed). 32 effects as shared resources.
- src/packs/ambient: the first pack — <Ambient effect="…"> mounts a registered
effect; the P contract (P-1..P-6) guarded by scripts/packs-check.ts; colors
are token-aware (P-4). One-way dependency, removable-by-construction.
- resolveToken extended to semantic color slots (--color-{role}-{slot}) so
consumers resolve theme tokens to concrete colors (the P-4 half).
STREAM B — animations over real text → canon
- Six components (count-up + text-{gradient,circular,blur,focus,scramble}):
each a morfo + eidos recipe (where there's styling) + demo. CountUp is a
service component (counts through uix.format.numbers). The five Text* are
passive decoratives. Upgrades over the seeds: SR hardening (real text
visually-hidden + aria-hidden decoration), a11y fix (no fake role=button),
measurement discipline (cached rects via dom.measure, no reflow storm),
reduced-motion, ecosystem citizenship (eidos.dom/timers, no raw platform).
- MorfoElement gains 'p'.
DOCS
- docs/architecture/packs.md (pack tier, admission rule, P contract, Aura
promotion path); docs/decisions/design-text-effects.md (the family design
record) + indexed in decisions.md / README.md; glossary entries
(scene/Ambient/Aura/text effects); scene README custom-pipeline + authoring
bridge; motion-guide content-effects note; strata tables acknowledge packs.
