- Reels spin a symbol strip inside a clipped reel window (drum shading),
never over the reel name or buttons
- Motion is a pure function of time: backward kick, launch, constant speed,
then a Hermite braking curve that lands exactly on the result symbol with
a small overshoot; staggered left-to-right stops
- No freeze on prefers-reduced-motion: the user's Windows reports it, which
left the strip frozen with overlapping symbols
- Compositor-only decorations (neon pulse, scanlines, landing flash) instead
of animated box-shadow/background-position that repainted every frame
- Scanline flicker kept on reel icons only; crisp monospace font instead of
Courier New
