/* ==========================================================================
   Night Grid — BWHamby.net
   Tile-based Ghost theme with tag tints and light/dark mode.

   TAG COLOURS
   Each tag gets a colour from its slug. To add a tag colour:
     1. add --tag-<slug> in BOTH the dark and light blocks below
     2. add  .t-<slug> { --a: var(--tag-<slug>); }  in the "Tag tints" block
   Tags without a colour use the main teal accent.
