/* Satellite shell: the chrome studio, analytics and the template store share --
   the left rail, the floating account button's place, the page scrollbars and
   the project / template card shell. ONE stylesheet for all three. studio-ui
   and analytics-ui import it from @kaleidr/landing-ui; template-ui ships a
   synced copy at customizer/vendor/satellite.css. Edit it HERE, then run
   03_code/.claude/scripts/sync-satellite-css.ps1 -Fix.

   Surfaces are soft: painted in the page's own color and lifted by a
   light/dark shadow pair instead of a fill and a border. Over a brand photo
   (sky / universe) the pair has nothing to read against, so the tokens below
   switch to a frosted surface, one drop shadow and tinted states. auth-core's
   account button and menu read the same tokens.

   Host contract: --s-bg, --s-primary and --s-text* from the theme scale,
   `data-theme` / `data-background` on <html>, --s-rail-w-collapsed, and
   --s-rail-w (the rail column's width, resolved by each host from the rail's
   `is-collapsed` state at its own phone breakpoint). --s-degraded-h, when a
   host sets it, pushes the rail and the account button below its banner. */
