/* Direction B, "Small jobs, big hours", fitted to teaching. Written Wed 4 Nov 2026 by Claude (builder B).

   size, one hot accent, Barlow body, Share Tech Mono only for dates. Used by index.html, library-m.html and work.html only;
   the older rooms keep shell.css. Fonts are self-hosted, SIL Open Font Licence (assets/fonts/OFL.txt). */
