/* =============================================================================
   Shared design system — The Question Method of Legal Research
   One source of truth for the interactive suite. Import on every page (hub +
   each module) so the look lives in one file.

   A clean, light neutral-gray ground, cool charcoal ink, and a single
   brick-crimson accent. Humanist sans for UI and body, mono for code/labels.
   Source types keep their own hues for taxonomy.

   Fonts are self-hosted (assets/fonts/) — no third-party CDN request, so the
   site leaks no student data to Google and renders identically offline.
   Archivo and IBM Plex Mono are licensed under the SIL Open Font License.
