   EnlaceVRC — Documentation styles (cyanotype theme)
   ========================================================================================================
   Mirrors the bot's own icon art: a deep ultramarine "blueprint / cyanotype" background with a subtle
   paper grain, bone-white text and glowing white accents, plus sparse red marks used only as a highlight
   (never for body text). Wiki layout: fixed sidebar + centered content. No build step, no framework.
