   Design tokens are CSS custom properties. The neutral theme below is the
   shipped default; bespoke/theme.json (server-validated) may override the
   --pa-* colour tokens only. The token set is a versioned interface
   (6.15.7): tokens may be added in later versions, never renamed.

   Colour token set v1:
     --pa-bg              page background
     --pa-surface         rail, cards, bubbles, inputs
     --pa-border          hairlines and input borders
     --pa-text            primary text
     --pa-text-muted      secondary text
     --pa-accent          brand accent: active nav, buttons, links
     --pa-accent-contrast text/icons on the accent colour
     --pa-user-bubble     user chat bubble background
     --pa-bot-bubble      assistant chat bubble background
     --pa-danger          destructive actions and error text
   Later additions: --pa-rail-bg, --pa-main-bg, --pa-tools-bg (round 3);
   --pa-rail-text (2026-10-30), the rail's plain text (captions and the
   footer) - it has no :root value, each rule falling back to the colour
   it had before; and --pa-rail-button / --pa-rail-button-text
   (2026-10-30), the solid rail pills.
