/* IGNITION / FURNACE shared mobile-first stylesheet.
   Leased to Claude under codex/0018-CLAUDE-PAGES.md. Same visual language
   as the existing OI Flow pages (see ui/css/root.css's palette), but this
   file is fully self-contained -- it does not depend on root.css loading
   first, so this page never silently breaks if a shared file changes.
   Mobile-first: base rules target 360px; min-width media queries add
   360->768->1440 layout. No fixed-width tables, no page-wide horizontal
   scroll -- wide content (book/timeline tables) scrolls inside its own
   bounded container only. */
