Complete CLI crystallization loop. Promote generates card_data (template slots, checklist steps, link URLs). Cards view sorted by use_count. Copy increments usage. Demote strips card layer. Delete does soft then hard. Edit opens $EDITOR.
Default command delegation: `nib "..."` routes to `nib add`. Capture bar parses grammar, creates entities. `nib ls` lists with date grouping, tag filter, 48h default window. Display glyphs for all entity types.
