   The chrome (header, gate, hero, transmission strip and footer) lives in
   css/cosmos.css, which loads after this file and owns the redesigned shell.
   What remains here is the interior of the pages.

   Written with logical properties (inline-start/end) throughout so the Arabic
   layout mirrors correctly without a second stylesheet. Where mirroring would
   be wrong — icon direction, the perspective tilt, the process rail — there is
   an explicit [dir='rtl'] rule rather than a blanket flip.
