/* Aazain Examination Portal — stylesheet.
   One file, no build step. Light and dark both defined via tokens.

   2026-11-09: brought onto the AAZAIN DESIGN SYSTEM
   (/srv/src/aazain-ui-standard/). Three layers:
     1. --aazain-*  source palette, from Website V2. Never themed. Components
        must NEVER read these directly.
     2. semantic tokens, defined once per theme in terms of layer 1.
     3. back-compat aliases — this file already had 130 var() uses under its
        own names, so every one of those names is kept as an alias of a
        semantic token. No rule below line 75 needed to change. This is the
        same pattern Sales Engine uses for its ~168 existing declarations.
   Theme order: light is the default (business/document portal); dark follows
   the OS and can be forced with data-theme on <html>. */
