/* ===========================================================================
   MultichannelTheme — multi-channel e-commerce admin dashboard theme
   One CSS file, no build step. Kept deliberately plain so you can drop the
   files on a server and they just run.

   Every colour lives in a custom property: edit the :root block alone and the
   whole theme takes on your brand.

   The dark blocks below read from --d-* first and fall back to the defaults.
   That is what lets assets/palettes.css swap the whole palette — light and
   dark — from a single rule per palette. Delete palettes.css and this file
   still works on its own.

/* Dark theme. Follows the system; an explicit data-theme choice wins. */
/* The doubled :root is deliberate. A palette rule in palettes.css is
   :root[data-palette="…"], which has the same specificity as a plain
   :root[data-theme="dark"] — and because palettes.css loads afterwards its
   light values would win in dark mode. Repeating :root outranks it, so these
   blocks stay in charge no matter which file loads first. */
