 * Landing page (logged out) and the Devise auth pages.

 * Everything here is prefixed .home-* / .auth-* so it cannot collide with the
 * app chrome in application.css or the record/dashboard styles in dash.css.
 * Colours are tokens only — the page has to survive the light/dark toggle.
 *
 * Corner geometry follows the house rule: every corner is a cut, never a
 * curve. Components set --cut locally and clip with var(--bevel); the
 * @supports block at the bottom hands the same cut to corner-shape where the
 * browser has it, so borders wrap the diagonal instead of being clipped off.
