/* Sealed, Delivered. — sign-in desk.
   Design handoff 2026-09-03: the stealth site's Classical skin (paper #f3f2f2, gold accent,
   plane red), a bordered card split by a single hairline. Left column = the real flow;
   right column = the seal panel.
   ⚠ The mock's left column was email + password and the right a QR "countersign". Neither
   exists: this product signs in by one-use magic link (src/auth.js) and there is no phone
   countersign to scan. A dead password field on a security product is worse than none, so
   the composition is kept and the columns carry what is actually true. The seal column is
   where a passkey/countersign step lands when the sealed-access work ships. */
