   isitlegal.cy — shared stylesheet
   ============================================================

   ONE design system, used by every page:
     - chat/ui.html              (search)
     - chat/deliberate.html      (deep analysis)
     - chat/about.html           (about)
     - chat/how_to_use.html      (instructions)
     - chat/corpus_page.py       (corpus inventory, server-rendered)
     - chat/article_page.py      (statute article, server-rendered)
     - chat/case_page.py         (case decision, server-rendered)

   Typography decision: two typefaces, two roles.
     - IBM Plex Sans   — all prose, all headings, all UI text
     - JetBrains Mono  — citations, statute references, metadata,
                         keyboard hints, anything where monospace
                         carries meaning
   No third "display" face. Plex has enough weight range and
   character to handle headings without help.

   Palette: cool slate base, near-black ink, single deep-indigo
   accent. Restraint is the point.
