/* AnywayDoor — Neo-Brutalist UI.
 *
 * House rules, applied everywhere:
 *   - 3px solid black borders, never hairlines
 *   - hard offset shadows with zero blur, so elements look stamped on the canvas
 *   - press = shift toward the shadow and shrink it, mimicking a physical push
 *   - flat saturated accents, color-blocked by section; no gradients, no blur
