/* ============================================================================
   Easy AI Agents — shared design system
   ============================================================================

   Every page used to carry its own inline copy of this file. Eleven copies, no
   single source, and they had already drifted: terms-of-service was missing
   --bg-elevated and a footer breakpoint that privacy-policy had. A rebrand meant
   editing eleven files and hoping.

   This is the one copy. Link it, do not paste it:
       <link rel="stylesheet" href="/css/system.css" />

   Page-specific rules still belong in that page's own <style> block, after this
   link. This file holds only what more than one page genuinely shares.

   ── Colour rule, do not break it ──
   --text-tertiary (#566159) measures 2.73:1 on --bg-surface and 2.46:1 on
   --bg-elevated. --text-faint (#3A4340) is worse. Both are below even the 3:1
   WCAG floor for large text, so NEITHER IS A TEXT COLOUR. Working backwards from
   the contrast formula, the dimmest compliant grey on these backgrounds is about
   #808080, which is already --text-secondary. A third accessible text tier does
   not exist on this palette. Subordinate text earns its rank from size, weight,
   letter-spacing and case, not from dimness.

   Both tokens survive for hairlines, decorative fills and disabled controls,
   which WCAG 1.4.3 exempts.
