/* ============================================================================
   LEX84 LABS — shared design system
   Single source of truth. Served by every app from /shared/lex84.css.
   Do not fork this file; app-specific rules belong in that app's own <style>
   block and should consume the tokens below rather than raw hex.

   Modelled on Apple's HIG: the platform font, semantic colour roles that flip
   with the colour scheme, hairline separators, restrained elevation, and
   generous whitespace. No webfont — SF on Apple devices, Segoe on Windows,
   Roboto on Android, all of which beat a 300ms render-blocking CDN request.
