/* ppi talk — Design-System v2
   Farben exakt aus dem offiziellen Logo gesampelt: Lila #523D91, Orange #E94B29, Graphit #4D4C4A
   Typografie: Poppins (Display — trifft die Logo-Schrift erstaunlich genau: "ppi" ExtraBold, "talk" Light)
               + Work Sans (Fließtext)
   Stil-Referenz nach Sichtung von 3st.de und territory.de: volle, gesättigte Farbflächen statt
   Pastell-Gradient und Karten-Schatten — EIN lauter Farbmoment pro Seite, Rest bleibt ruhig. */
