Juice.gd — the feel system, driven off Smashable.smashed (purely additive):
- Hitstop freeze-frame on every impact (time_scale dip, released in real time)
- Screenshake with quadratic trauma falloff, scaled by shard count
- Per-material GPU particle bursts, colored from the PROFILES table
- Procedural impact audio synthesized in code per material — no sound files,
the dig.js trick: wood crunch, cardboard rip, vinyl crack+warble, glass tinkle, steel ring
- Combo counter on the HUD
