/* CT Foundation Manual — Contents Hub (fm-hub.css)
   Same tokens as fm-reader.css (CLAUDE-design.md). #111111 dark, Inter + IBM Plex Mono.
   Amber budget (STRICT): exactly two amber elements on this page —
     .btn-primary (resume button) + .highlight (the "binabasa" part row).
   Everything else is brightness vs dimness. No green. No shadows. No gradients.
   Mobile-first. 640px canonical breakpoint. 44px min tap targets.
