/* ==========================================================================
   Mine platform console component layer (c- prefix)
   --------------------------------------------------------------------------
   Load order:
     vendor/tabler.min.css
     app-design.css          (owns --ink/--muted/--accent/--line/--paper)
     console-ui.css          (this file: tokens + components)
     console-shell.css       (topbar + page shell)
     <page>.css              (page layout only, tokens only)

   Rules:
   - Every colour lives in the :root token block below. Component rules use
     var(--c-*) and never raw hex values.
   - Selectors are namespaced with .c- so Tabler, Tabulator and SweetAlert2
     keep their own styling. Never add bare .card/.btn/.table/.modal rules.
   - No web fonts, no @import, no remote assets.
