Light slaps now trigger a spring wobble (using the previously unused
SLAP_IMPULSE constant) with a cartoony synthesised boing sound.
Only 3 rapid slaps within 2s escalate to the full ragdoll fall.
- Spring wobble: kicks slapVelocity on light tap, damped spring
produces visible head/body oscillation
- Synthesised boing: 3-layer Web Audio (noise pop + sine sproing +
triangle harmonic) for satisfying cartoon spring sound
- Pip startle scales proportionally: mild scatter on wobble (1.5s),
maximum scatter on ragdoll (5s)
- Crystal flash scales: 0.25s for wobble, 0.5s for ragdoll
