flemming-it
1be2ad075d
The compact chips under the heatmap showed only [Tier-Badge] jurabk paragraph (e.g. 'T4 GewO § 14'), which was enough for a methodologically oriented reader but not for someone scanning 'what was that pilot norm about?'. Adds a muted mid-dot + the norm.title after the paragraph, so each chip now reads: T4 · amtlich GewO § 14 · Anzeigepflicht The chips stay clickable, navigation behaviour unchanged.
