 * @description The landing page's way in: a headline, the let-your-AI-do-it box, and the register and sign-in
 *   doors. Drawn by components/FrontDoor.js. Reads only the tokens in theme.css and the shapes in
 *   poster.css; a page never styles it from outside.
 * @usage Linked from public/spa.html in the component block, whose order keeps the order these
 *   rules had when they were one sheet.
 * @version-history
 *   v1.0.0 — 2026-09-23 — Moved unchanged from css/parts*.css (UI consolidation phase 1, a move).
