/* Drum composer.
 *
 * Theme-aware throughout: colours come from the palette tokens in
 * color_palette.css (--cloud-bg for panels, --surface-* for edges, --text /
 * --number for type), which applyTheme() swaps on <html>. Nothing here hardcodes
 * a light or dark value except the gold accent, which is the same in both.
 *
 * Hits are an opacity ramp on that one gold rather than three separate colours,
 * so ghost < normal < accent reads as intensity and stays legible over either
 * panel background.
 *
 * The step grid is the whole screen on a phone: 5 drums x 32 steps is 160 tap
 * targets, so the grid scrolls horizontally inside its own container and the
 * page body never does. Cells keep a real touch size rather than shrinking.
