/* ==========================================================================
   CityWorkshop — Premium SaaS Design System (CWS_V_5_Fixed_7.6)
   --------------------------------------------------------------------------
   Loaded LAST, after every other stylesheet (swiggy-premium, crystal-3d,
   and the many prior override layers already in cws-bundle.opt.css). This
   is intentional: the codebase already has substantial indigo/violet,
   glassmorphic, and "3D press" button styling scattered across several
   earlier iterations. Rather than add yet another layer that half-fights
   them, this file is the canonical, final word — it unifies what already
   exists and fills the genuinely missing pieces:
     - a single consistent token system (colors, radius, shadow, blur, motion)
     - real dark mode (toggle + persistence + system-preference default) —
       did not exist anywhere in the project before this
     - accessible focus-visible rings — did not exist anywhere before this
     - a skeleton loading state for the boot screen — did not exist before
     - a ripple micro-interaction on every button
     - consistent modern checkboxes (appearance:none, custom check mark)
     - a consistent card/badge/toast finish across every role

   Pure CSS + one small JS behavior file (premium-saas.js) for ripple.
   Dark mode's no-flash-of-wrong-theme script lives inline in index.html
   (must run before first paint). Nothing here removes functionality —
   it is a finishing layer over the existing DOM structure and classes.
