   MANGO LAKE — brand foundations and the two-world shell.
   Tokens and shell styles are lifted from the blessed exemplar
   (docs/working/visuals/lake-ui-redesign.html). One Swiss-modern
   system, two registers: the white consumer catalogue topline and
   the navy-banded /platform operations worksheet. Square corners,
   hairline rules, no decoration.

   SIGN-IN — the split gate (and accept-invite in the same
   register). Ported from the blessed exemplar's gate block
   (search `viewAccess` / `.gate` in docs/working/visuals/
   lake-ui-redesign.html), kept in the exemplar's compact
   notation for line-by-line traceability. Adaptations only:
   `--mono` → `--lake-mono`; the primary action is an anchor to
   the real OIDC round-trip; the entrance fade sits behind
   prefers-reduced-motion. Unauthenticated sign-in is a
   full-height 45/55 split: the real boundary-glow image left
   (scrimmed navy like the landing hero) carrying the
   "Invitation only." statement, the functional column right,
   vertically centred. Primary action is unmistakable; invite
   redemption is a ruled secondary block in the same column; the
   API-key path stays a quiet tertiary disclosure. Square
   corners, hairlines, Swiss register.
