   Atlas AI — Midnight Design System
   Dark-only, permanently. Built from scratch.

   Loaded after tokens.css and shell.css, which provide the
   updated palette and the new sidebar / topbar / drawer shell.
   This file still owns the legacy component styles
   (cards, buttons, forms, page-specific layouts) and will be
   broken out into smaller modules in a follow-up PR.
