feat: Wave 9.E (ai-ui@0.6.0) + Wave 13.D.1/.5 (motion@0.2.1)
──────────────────────────────────────────────────────────────────
motion@0.2.1 — Parallax + TiltGallery
──────────────────────────────────────────────────────────────────
+ Parallax.tsx
- scroll-driven translate3d via rAF + window.scroll
- speed multiplier + axis (y / x) + reduced-motion bypass
- listener cleanup + cancelAnimationFrame on unmount
- WAVE 13.D.1
+ TiltGallery.tsx
- horizontally-scrolling rail of <TiltCard>-style tiles
- per-tile cursor-tracking rotateX/Y + glare gradient
- role=region + arrow-key scrolling (←/→) + scroll-snap
- reduced-motion strips tilt + glare, keeps the rail
- WAVE 13.D.5
+ 5 new tests (Parallax x 2, TiltGallery x 3) — 28/28 passing
+ index.ts: exports both + types
+ package.json: 0.2.0 → 0.2.1

ai-ui@0.6.0 — Wave 9.E composition surfaces
──────────────────────────────────────────────────────────────────
+ Markdown.tsx
- dep-free subset renderer: h1-h3 / **bold** / *italic* /
`code` / fenced code / ul + ol / [text](url)
- inline `[cite:<id>]` chips resolved from a citations
registry (missing ids render as [?] — failure mode is loud)
- WAVE 9.E.1
+ CodeDiff.tsx
- line-LCS diff in <100 LOC, zero deps
- split (2-col) and unified views; tinted add/del rows
- WAVE 9.E.2
+ ExplainThis.tsx
- listens for selectionchange, pops 'Explain' CTA over the
selection rect when inside the wrapper + ≥ minLength chars
- fires onExplain({ text, rect }) so hosts can open a richer
side panel if preferred
- WAVE 9.E.3
+ usePromptHistory.ts
- bash-style ↑/↓ recall with localStorage persistence
(storage key configurable; null = in-memory for tests/SSR)
- dedupes consecutive duplicates + trims to capacity
- WAVE 9.E.4
+ useTokenCount.ts
- cheap estimator (default ~4 chars/token; configurable for
code/CJK) + optional USD cost
- memoised — stable across re-renders
- WAVE 9.E.5
+ 19 new tests in src/__tests__/composition.test.tsx — 98/98 passing
+ index.ts: '0.6 surfaces' section exports all 5 + types
+ package.json: 0.5.0 → 0.6.0
Showcase routes + roadmap flips land in the paired showcase commit.
