feat(skills): remotion-to-hyperframes corpus T3 (4/7)

Adds the data-driven tier — a purpose-built fixture (option 2 from the stack discussion, not a port of PR #214's examples/remotion-full/) that exercises the realistic shape of a production Remotion composition without using the runtime adapter. Stargazed.tsx (10s @ 30fps, 1280x720): Sequence 0-3s TitleScene (title + subtitle) Sequence 3-7s StatsScene (3 reused StatCards staggered 12 frames apart) Sequence 7-10s OutroScene (UnderlinedText with scaleX-from-left underline) Composition shape exercises: - <Composition schema={z.object({...})} defaultProps={...} /> - nested array prop (stats[]) materialized as repeated HTML - custom React subcomponents (StatCard, AnimatedNumber, UnderlinedText) reused with different props - per-instance delay via prop (delayInFrames -> GSAP timeline offset) - frame-driven count-up (AnimatedNumber, manual cubic ease-out) - two different spring configs in the same composition (damping:12 -> back.out(1.4), damping:14 -> back.out(1.2)) - useCurrentFrame, useVideoConfig Translation choices documented in README.md and expected.json: - Zod props -> data-* on root #stage div - Custom subcomponents inline as repeated HTML using prop interface as the template - AnimatedNumber's frame-driven count-up -> GSAP onUpdate tween on a { v: 0 } counter object, ease power3.out - Two different spring configs -> two different back.out overshoots (1.4 vs 1.2 approximates the damping difference) - delayInFrames={i * 12} -> GSAP offset (i * 0.4)s Validated end-to-end: rendered Remotion baseline + HF translation, ran scripts/render_diff.sh. measured mean SSIM 0.953 measured min SSIM 0.927 measured p05 SSIM 0.938 threshold 0.90 (~0.04 below p05) The wider gap vs T1/T2 reflects T3's bigger approximation budget (2 spring instances + count-up timing + font fallback on multiple text sizes). Mean SSIM below 0.90 = structural mismatch (wrong durations, wrong stagger, missing prop wiring), not approximation drift. Same Remotion config as PR 3: setVideoImageFormat("png") + setColorSpace("bt709") to match HF's yuv420p output. Lint: 9 files scanned, 0 blockers / 0 warnings / 0 infos. oxlint, oxfmt, typecheck all pass. The fixture is not yet wired into CI; render + diff is documented in README.md and runs by hand via the harness from PR 2. PR 7's orchestrator will wire all four tiers into a CI eval run.

+# Tier 3 — stargazed-data-driven
+
+## What it tests
+
+A purpose-built data-driven fixture that exercises the realistic shape of a
+production Remotion composition without using the runtime adapter from
+PR #214. If a translation passes T3, the skill correctly handles:
+
+- A `<Composition>` with a `z.object` schema and typed `defaultProps`
+- Custom React subcomponents reused with different props across scenes
+- A nested data structure (`stats[]`) materialized as repeated HTML with
+  per-instance attributes
+- A frame-driven count-up animation (`AnimatedNumber` → GSAP `onUpdate`)
+- Two different `spring` configs translated to two different `back.out` overshoots
+- Per-instance delays via component props (`delayInFrames` → GSAP timeline offsets)
+
+## Composition shape
+
+```
+Stargazed (10 s @ 30 fps, 1280×720)
+├── Sequence 0–3 s   TitleScene
+│                    ├── title  ← spring scale
+│                    └── subtitle ← linear fade
+├── Sequence 3–7 s   StatsScene
+│                    ├── StatCard "Stars" 1247 #fbbf24 (delay 0 frames)
+│                    ├── StatCard "Forks" 312 #60a5fa  (delay 12 frames)
+│                    └── StatCard "Issues" 48 #f87171  (delay 24 frames)
+└── Sequence 7–10 s  OutroScene
+                     └── UnderlinedText "thanks for watching" ← scale-in underline
+```
+
+Each `StatCard` is a custom subcomponent that internally uses `AnimatedNumber`
+to count from 0 to the target. `AnimatedNumber` itself derives the displayed
+value from `useCurrentFrame()` + a manual `1 - (1 - t)^3` ease.
+
+## The lossy parts (and why threshold = 0.90)
+
+1. **`spring → back.out(N)`**: two different spring configs in this composition.
+   - `{ damping: 12, stiffness: 100, mass: 1 }` (title) → `back.out(1.4)`
+   - `{ damping: 14, stiffness: 90, mass: 1 }` (stat card) → `back.out(1.2)`
+
+   Overshoot ratio (1.4 vs 1.2) approximates the damping difference. The
+   late-tail curve of GSAP's back ease and Remotion's spring don't match
+   exactly — costs ~0.03 mean SSIM per spring instance.
+
+2. **Count-up easing**: `AnimatedNumber` uses `1 - (1 - t)^3` (cubic ease-out)
+   manually computed in the component. GSAP's `power3.out` is the same curve
+   shape — should match closely. The displayed integer is rounded each frame
+   in both renderers; minor mismatches occur when the rounded value flips
+   between two numbers on a sub-frame timing difference.
+
+3. **Font rendering**: same caveat as T1/T2. System Helvetica/Arial fallback
+   produces minor anti-aliasing differences between renderers. Affects the
+   stat card numbers (large weight 800) most.
+
+A mean SSIM below 0.90 in T3 indicates a _structural_ mismatch (wrong scene
+durations, wrong stagger timing, missing prop wiring), not approximation
+drift. That's the failure signal we care about. The calibrated mean against
+Remotion @ 4.0 with PNG/BT.709 output is 0.953.
