/* © 2026 Juan Pazmino B — Claude Code Digest chat widget.
   Lives only inside public/index.html, so unlike the sibling widget on
   juanpazminob.com this does NOT redefine its own --cb-* palette — it reads
   the page's existing --gold-rgb / --text-rgb / --shadow-rgb tuples and the
   --surface/--gold/--gold-hi/--cream/--muted vars declared in index.html's
   :root and [data-theme="light"] blocks, so both themes stay in sync
   automatically with zero duplicated color logic.
   Typography note: index.html only loads Fraunces at weights 100/300/400,
   non-italic. The source widget (juanpazminob.com) sets message text in
   italic Fraunces 200 — those weights/styles aren't loaded here, so this
   version uses Fraunces 300 upright instead of adding a new font-weight
   axis to the shared Google Fonts import. */
