/* ==========================================================================
   Urban Coding Labs — site stylesheet
   --------------------------------------------------------------------------
   Identity: engineering dossier. Bone-coloured paper, ink, one oxide accent,
   hairline rules, monospaced indices. The visual language of a spec sheet
   rather than a landing-page template.

   Type: Bricolage Grotesque (display) / Source Serif 4 (reading) /
   Azeret Mono (labels). Windows-only fallbacks are declared so the page still
   looks deliberate when the webfonts never arrive.

   Section order mirrors the HTML. Variables at the top are the only part the
   admin panel rewrites at runtime (see applyTheme in js/site.js).
