/* =========================================================================
   MLH Brand Design System
   New, hand-written stylesheet — not derived from the vendor theme.
   Loaded after main.css in base.html.

   1. Token override  — recolors/refonts every existing vendor utility class
      (bg-main-600, text-main-600, btn-main, section-heading, ...) across
      every page that shares base.html, with zero markup changes.
   2. New `mlh-*` components — bespoke markup for the rebuilt public shell
      (nav, footer) and homepage. Prefixed to guarantee no collision with
      the vendor file's classes.
