feat(keys_highway_3d): hit FX — vibrancy, timing-colored sparks, hit-line kick (K2) (#699)
- Note vibrancy: gem opacity 0.8 -> slider-driven (default 0.92), NOTE_EMISSIVE_BASE 0.08 -> 0.22, lane guides scale with the slider, _applyVibrancy retints the live scene without a chart rebuild - Sparks (PORTED highway_3d, pool 96) at the struck key, colored by _timingHex/_classifyTiming (±100ms window, inner 40% = on-time; delta recovered from judgeHit's noteKey prefix — contract untouched); streak-scaled counts - Hit-line brightness kick on scored presses (exp(-t*6) decay, hitFx slider), folded into the existing pulse incl. the bloom damp gate - Settings: Hit sparks / Timing colours / Streak feedback + Hit feedback intensity + Note vibrancy sliders (keys3d_bg_*, live-applying) - Tests: classifier boundaries, noteKey time round-trip, FX defaults (26 total) Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
