   IESMAC ERP — Material skin over Phoenix Bootstrap 5.3
   SPRINT 3 · Surfaces: Modals, Offcanvas, Popovers, Tooltips, Toasts
   ----------------------------------------------------------------------------
   Depends on: material-skin.css (Sprint 1) — for tokens
   Load order:
     1. theme.min.css        (Phoenix core)
     2. user.min.css         (empty Phoenix slot)
     3. style.css            (existing tweaks)
     4. material-skin.css    (Sprint 1)
     5. material-skin-surfaces.css   ← THIS FILE

   ════════════════════════════════════════════════════════════════════════════
   TENANT THEMING NOTE — important for future
   ════════════════════════════════════════════════════════════════════════════
   This file uses ONLY --md-* CSS variables. No hex literals in component rules.
   That means a future tenant-branding system can override the brand by injecting
   a single <style> block in the layout head, like:

     <style th:if="${currentTenantBranding}" th:inline="text">
       :root {
         --md-primary-40: [[${tenantBranding.primaryHex}]];
         --md-primary-30: [[${@colorUtil.darken(tenantBranding.primaryHex, 15)}]];
         --md-primary-90: [[${@colorUtil.tonal(tenantBranding.primaryHex, 90)}]];
         --md-primary-95: [[${@colorUtil.tonal(tenantBranding.primaryHex, 95)}]];
       }
     </style>

   Every modal, popover, toast, etc. in this file will recolor automatically.
   For tonal stop calculation, consider Google's material-color-utilities
   (Java/MIT) as a Maven dependency.
