/* Reblium Studio manual. One stylesheet for every page under web/docs/.
   Dark, the same tokens as about.html and the shelf. The left rail is
   FIXED and scrolls on its own (Leonardo: "keep our left nav bar always
   visible"), the way the Blender manual keeps its tree. No build step: every
   page is served as written; docs.js draws the rail from nav.js. */
