   GEOPHORA — Umfrage-Stylesheet (gemeinsam für /umfrage/ und
   /waermeplanung/umfrage/)  ·  Stand 2026-08-11
   Ersetzt die beiden byte-identischen styles.css-Duplikate. Farben nach dem
   Familien-Design (Untermarken-Beschluss 2026-08-11): Boden, Tinte und
   Haarlinie = „Kühle Kreide" von robertrettig.de; Akzent bleibt das
   GEOPHORA-Blau. Schrift: Inter (Einbindung über assets/fonts/fonts.css
   im jeweiligen HTML-Kopf). Selektoren und Markup unverändert — die
   laufende, token-basierte Befragung bleibt funktional unangetastet.
