   Design-System v3 „Klinische Referenz“
   Referenzniveau: AMBOSS · UpToDate · Ada Health · NICE (digital products)

   Prinzipien:
   - Produkthafte Kartenarchitektur mit weicher Tiefe (mehrschichtige,
     niedrig-opake Schatten) statt Haarlinien-Broadsheet.
   - Editoriale Serife (Source Serif 4) für Titel = medizinisch-publizistische
     Gravitas; Inter für UI/Fließtext; tabellarische Ziffern für Daten.
   - EIN Aktionsblau (klinisch, vertrauensbildend) + funktionales BtM-Gelb,
     abgeleitet vom gelben BtM-Rezeptformular (Muster 8) — nur für
     BtM-spezifische Marker (Warnungen, „A“-Kennzeichnung, Rezept-Panel).
   - Radius-Skala 8/12/16, ruhige Flächen, großzügiger Weißraum.
   - HTML-Klassenverträge und JS unverändert; reine CSS-Neuinterpretation
     (+ Hero-Panel auf der Startseite).
