 * Custom CSS that supplements Tailwind utility classes.
 * Everything here is either:
 *   (a) a structural pattern too dynamic for static Tailwind classes, or
 *   (b) a browser-level override that Tailwind cannot express cleanly.

 * All colour values reference CSS custom properties from style.css :root.
 * Never add raw hex values here — use var(--color-*).
