Sample View

One take on a seconds axis from host-prepared data only: min/max peaks on a canvas, a PreparedSpectrogramData heatmap (magma, log frequency) or both, with a Wave / Spectrum / Both toggle. Draggable, keyboard-steppable start/end and loop handles report take-normalized positions; playheads; a dimmed extension past the take end; a seconds ruler; and an overlay slot whose children read the same geometry from context. The axis latches during an overlay drag. The canvas repaints only when its peaks, colour or size change.
