The icon card renders each glyph at a hero size plus a continuous sample
strip (10–48px) so legibility is judged at the sizes the app uses, with the
entry's optional label + description and a per-entry or card-level color.
Wired end to end: icon.show publishes on the `icon` bus, the Claude
extension injects an IconMessage, and conversation_view paints the card
(display-only, D-78). en+nl catalogs.
