/*
 * ROSE'S design system v1 -- Workshop Dark (site and app).
 * Source: ROSES_Design_System.pdf. Every colour, size, duration and easing
 * below is taken from it; change them HERE, not in individual pages.
 *
 * Rules from the system:
 *  - One rose (--acc), spent carefully: primary button, selected border,
 *    tags, the strop line and focus. Never large areas.
 *  - --line is decoration only; anything you can press or type in uses
 *    --line-strong.
 *  - 3px corners everywhere. Only ticks and dots are round.
 *  - No shadows. The only "shadow-like" thing is the focus ring: a 2px
 *    ground-coloured gap, then 2px of rose.
 *  - Four motions only (rise, strop, pole, tick). With reduced motion on,
 *    every move is instant and the pole stands still.

/* ---------- Fonts ----------
 * Mono: IBM Plex Mono (SIL Open Font Licence), served from public/fonts/
 * (see public/fonts/README.md). To change the font later, add the new
 * files there, point the three @font-face rules below at them and update
 * --mono in :root. Also update MONO in lib/customer-emails.ts.
 * Sans: the design's sans face isn't confirmed yet -- set --sans below once
 * it is. */
