/* ══════════════════════════════════════════════════════════════════════
   VELYRON · Artifacts — a shared live canvas for generated files.
   The model emits ```velyron-file {json}``` blocks; these render as cards
   in the conversation and open a right-side canvas that coexists with the
   chat (side-by-side on desktop) and live-updates as the agent works.
   Relies on host CSS vars: --signal, --fg, --fg-dim, --fg-mute, --bg,
   --bg-1, --rule, --rule-2, --scrim. Both AUGUR and Agents define these.
