/* ============================================================================
   AI Warden — web_prod design system
   ----------------------------------------------------------------------------
   Single source of truth for tokens, typography, layout primitives, and shared
   components. Imported once per page via <link rel="stylesheet" href="/assets/
   css/site.css">. Loads in this order:

     1. tokens.css         — colours, type scale, radii, motion, z-stack
     2. base.css (this)    — reset + typography + layout + components

   Aesthetic stance: dark, premium, restrained. Editorial scale on hero copy,
   monospaced numerics on data, glass surfaces with subtle gradient borders,
   and animated entries that respect prefers-reduced-motion. The site uses
   limited inline `style=""` for data-driven values (bar widths, etc.) — if a
   strict CSP is needed on the host it can be solved with a per-build hash
   pass or by lifting those inlines into utility classes.
