/* ============================================================
   LAYT — Compass shell
   Self-contained styles for the spatial navigation that wraps the
   landing (embedded at "/landing.html"). Matches the landing's own
   type system (Syne wordmark, Helvetica body, mono labels) and does
   NOT depend on the portfolio's global.css.

   Progressive enhancement:
     - no JS         → panels stack in normal flow and scroll.
     - html.js-compass → fixed spatial stage; one panel at a time.
   Mode tokens (--c-*) allow a future Compass/Cinematic mode; only
   Editorial ships.
