/* RocketHour Docs — shared theme + app shell for the internal knowledge base.
   Intent: a WORK TOOL with personality — dense + scannable, but alive (brand colour,
   gradient accents, motion, clear section markers). Persistent left sidebar = the nav
   (Category › System › Section, scroll-spy). Built by kb.js from systems.json + the
   page's own <section> headings, so it stays DRY. Tooltips (.tt) carry extra detail. */
