/* ==========================================================================
   Digital Scribes — Light vs. Darkness theme

   All colors live here in :root. The -rgb variants are channel triplets so
   alpha variants can derive from the palette via rgba(var(--x-rgb), a).
   ClojureScript reads these too (see particles.cljs), so this block is the
   single source of truth for the theme.
