/* ==========================================================================
   MUCO LABS — Design System
   Built to MUCO_LABS_PAGE_BY_PAGE_UI_UX_MASTER_SPEC.md

   Direction (spec §2): premium technology studio + engineering lab + serious
   business partner. Not a template, not a purple-gradient SaaS clone, not an
   over-animated award site.

   Palette (spec §3.1): obsidian and graphite surfaces, warm ivory text, one
   muted copper accent. Secondary colour only where it carries meaning —
   status, warning, error — never as decoration.

   Background (spec §4): layered depth rather than a flat black sheet. A base,
   a low-opacity light source, grain, architectural linework in selected
   sections only, an occasional accent bloom, and a vignette.
