/*
 * DriftEdit design tokens.
 *
 * A contemporary pro-tool palette: layered neutrals with a faint cool bias, hairline edges instead
 * of heavy borders, and colour used by role, the way editors already read it:
 *
 *   --accent   interactive things: the primary action, focus, toggles, sliders, the active tool
 *   --select   the selection on the timeline and the playhead: white on dark, ink on light
 *   --beat     musical information only: beats, bars, song sections, the auto-mode window
 *   --clip-*   what a clip is: video, audio, text, effect, adjustment
 *
 * The viewer's stage stays neutral (no hue) because colour is judged against it.
 *
 * Dark is the studio's default and lives on bare :root. Light follows the OS when the theme is
 * "system" (no data-theme) and is forced with data-theme="light"; "contrast" is high contrast.
 * The accent is azure (Dario's choice). Every text pair is checked against WCAG 2.2 AA in
 * README.md.
