   ============================================================================
   Theia Fiber AI design tokens. Include this stylesheet in every console
   module so colors, spacing, fonts, and component primitives stay aligned
   across the platform.

   Inclusion order matters:
     1. theia-tokens.css       (this file)
     2. <module>.css            (module-specific styles)
     3. inline overrides        (rare; document why)

   Tokens are CSS custom properties on :root. Override per-module by setting
   them on a narrower scope, but never hardcode hex values in component CSS.

   Light theme is default. Dark theme is reserved for marketing surfaces
   (landing page, sign-in) and is NOT used in console modules.
