/* Materials — developer-docs markdown viewer (route #materials).
   Migrated out of the legacy monolith and fully tokenized: themes correctly in
   light AND dark from the canonical token set (no !important patches needed).
   Class names unchanged — the page JS (js/pages/materials.js) binds to them. */
