/* =====================================================
   WILDCAT DESIGN SYSTEM
   Implements the "Wildcat Bot UIs" handoff spec.

   Source of truth: the wildcat-design-system repo. Each
   app's copy is written by `npm run sync:design-system`
   and `npm run check` fails if it drifts, so do not edit
   the copy in an app. Keep this file free of rules that
   only one app's markup uses;
   those go in the app layer (chatsage-specific.css /
   chatvibes-specific.css), which loads after this file.
   Load order in both apps: reset.css, custom.css (theme),
   this file, app layer; WildcatTTS also loads base.css
   (the Bootstrap-era element and component bases) before
   custom.css. Neither app loads Bootstrap: section 14 is
   the utility shim that replaces it. The few !important
   flags outside the shim exist because the shim's .text-*
   utilities are !important, as Bootstrap's were, and a
   component rule that must recolour such an element has
   to match that.
   Section 1 redefines the shared tokens (and remaps the
   legacy names onto them) so the theme rules in custom.css
   inherit the new palette. Sections 2+ add the components
   the spec introduces.

   Two values differ from the spec sheet, both to clear the
   project's WCAG AA bar; hue and role are unchanged:
     text-3   dark  0.545 -> 0.630   (was 3.19:1 on surface-2)
              light 0.560 -> 0.537   (was 4.09:1 on surface-2)
     border-strong  new token at 3:1 for control outlines;
                    --wc-border stays at the spec value and
                    is used only for decorative hairlines.
