/*
 * The signup experience, in Kard Kulture's own visual identity.
 *
 * ── Why this file was rewritten ────────────────────────────────────────────
 * This service renders the only pages a campaign visitor sees between the
 * marketing site and their inbox: /early-access, the confirm page their email
 * link opens, and the confirmed state. Those pages are served from the same
 * origin as the marketing site, under the same domain, in the middle of one
 * journey — so they have to be the same product, not a form that happens to
 * live at the same address.
 *
 * The previous stylesheet was a different product: #0b0b12 ground, three
 * animated purple/teal aurora blobs behind a blurred glass card, and a
 * gradient clipped through the headline. Kard Kulture's identity is the
 * opposite of all four — warm ivory paper, one serif, flat surfaces, and
 * colour reserved for Kards and deck covers where it carries meaning.
 *
 * ── Where these values come from ──────────────────────────────────────────
 * Every token below is copied from `site/src/styles/global.css`, which is
 * itself pinned by `site/tests/tokens.test.mjs` to the app's own
 * `src/design/tokens.ts` and `theme.ts`. The dark grounds are Minimal Luxe's
 * night, because that is what the app actually renders. Sage is the only
 * accent, and only for a focus ring and a link underline.
 *
 * Kept deliberately: `.wrap`, `.skip`, `#main`, the form's ARIA hooks, and
 * the mobile/focus/motion/forced-colours rules that `tests/test_v11.py`
 * asserts on. The identity changed; the accessibility contract did not.
