tid_ocean_mat

Gerstner ocean material for the tides part (shader: tid_ocean), applied to the Geo.grid sea mesh spawned by p5_tides. The part drives game_t, music-reactive amp_scale / glitter_boost / sss_strength, and the foam0/foam1 collar points that follow the chrome ring's waterline as it turns; foam2..foam4 mark the glass monolith bases.
