/* ═══════════════════════════════════════════════════════════════════
   LOADERS — css/components/loaders.css
   ═══════════════════════════════════════════════════════════════════
   Three tiers, in this file:
   1. Base primitives   — spinner, dots, skeleton, progress bar, inline
                          loader, button loader. Used everywhere.
   2. Boot loader        — the one-time emblem shown on first load after
                          login while initial dashboard data streams in.
                          Markup lives in index.html (#boot-loader).
   3. Task loader system — reusable full-screen overlay for long-running
                          module actions (save, payment, report
                          generation, etc). Markup is injected at runtime
                          by js/ui/loaders.js into #task-loader-overlay.

   No pure white (#FFFFFF), no pure black (#000000).
