/* The door — sign-up, sign-in and the code (docs/DESIGN.md §22,
   2026-10-12). Linked by saas/shared/_door alone, over the company sheet
   and the landing sheet (the drawn themes, the orb, the spectrum). Light,
   split in two: the stage — the mark, a still collage of what a
   publication is, the headline — and the form in a paper panel behind a
   hairline. Nothing moves: no animation, no transition, no tilt (Ronald:
   the first cut's motion made him sick). No script. */
