/* ============================================================
   LANDING — the signed-out front door, from Rob's approved design
   packet (Orchestration ops/design/lake-ui-packet.md and
   lake-landing.html, 21 October 2026).
   Square like the map's blocks: 3px corners for controls, 4px for
   surfaces, no pills or circles. One tab style, one outline for
   controls on navy, one hairline, one glass and one shadow, all
   held in the tokens below so later components share them.
