When a drum pad fires, capture the exact per-voice params sent to sound.synth() (type, tone, attack, decay, volume, duration) and display them in a compact panel above the drum grid. Each voice is rendered as a colored card tinted by wave type (sine=blue, noise=grey, etc.) with abbreviated params: "N2.5k a0 d2 v50" = 2.5kHz noise, 0ms attack, 2ms decay, 50% volume. Inspector fades out over ~5 seconds. Phase 1 is read-only — later phases will let you drag each param with the mouse/trackpad to dial the sound in per-pad.
