/* ──────────────────────────────────────────────────────────────
 * Canter.Health — marketing site
 *
 * Tokens are copied verbatim from the app's own v2 design system,
 * src/design/v2/src/tokens/ in the Canter-Health/Canter repo. That is the
 * authoritative source: the site and the product share one vocabulary,
 * so a value lifted from either resolves in the other.
 *
 * The brand hue is rose --brand-600 #C22551, sampled from the ECG trace
 * in the app icon. v2 deprecates the earlier oxblood #7A2E2E (kept there
 * only as --ox-* aliases), and the interim brick #B3342F this site used
 * before the logo was updated is gone with it.
 *
 * Contrast, verified against these exact pairings:
 *   white on --brand-600 (button fill) 5.71:1
 *   --brand-600 on --n-50 (link, figure) 5.31:1
 *   --brand-700 on --n-50 7.07:1
 *   --n-500 muted text on --n-50 5.10:1
 *   --brand-200 on --brand-800 (inverse band) 6.5:1
 *   status chips (600 on its own 50 tint) 5.4:1 or better
 * All clear WCAG AA. --brand-300 #EB8290 is 2.58:1 on white and is an
 * accent only — it must never carry text or a button fill.
