/*
 * Quartet synth window: layout only. Colours, panel, knobs and LEDs come from the
 * shared analog look (../analog.css) and the app's role tokens, so it follows every
 * skin and theme. 15px text floor, 44px touch targets on touch screens, no sideways
 * page scroll. Compatibility: no @layer, color-mix(), oklch(), :has(), container
 * queries or nesting (Chrome 95 / Safari 14).
