/* ===========================================================================
   RoxTribe resources theme — FULL DARK, RoxTribe palette.
   Single source of truth for article visual styling so every engine-authored
   fragment stays consistent WITHOUT per-fragment color hardcoding. Fragments are
   authored as semantic HTML (h2/h3/p/ul/table/blockquote) plus the .rox-*
   component classes below. Everything is namespaced under .rox-prose / .rox-* so
   it can never leak into the dark global theme.

   Palette: gold #FFD700 · silver #C0C0C0 · black #000 · near-black #0a0a0a
   See specs/content-engine/references/color-conventions.md for the contract.
