/* ==========================================================================
   NexiBook Design System — Polish Pass v1
   Date: 2026-04-19
   Scope: tenant + trainer + customer surfaces (all of booking app)

   Goal: visual refinement ONLY. Zero HTML mutations, zero new routes,
         zero business-logic impact. Applies on top of legacy CSS as a
         last-loaded stylesheet — wins the cascade naturally without
         !important on anything except where Bootstrap brute-forces a bg.

   Load order (per partials/header.ejs and customer/layout.ejs):
     /ds/colors_and_type.css    (tokens + Inter/DM Serif/Plus Jakarta)
     /ds/admin_palette.css      (admin surfaces only — indigo override)
     /css/style.css             (legacy)
     /css/sintra-theme.css      (legacy)
     /css/dashboard-premium.css (legacy)
     /css/design-system/tokens.css + components.css + animations.css (older DS)
     /css/theme-utilities.css
     /css/components/*.css
     /css/design-system/polish-v1.css  ← THIS FILE (last, wins)

   To remove: delete the two <link> tags referencing this file from
     views/partials/header.ejs and views/customer/layout.ejs.
