/* ============================================================
   Ulli ist Supi — Brand-Foundation v2 (Pack 3b)
   Stand 2026-05-12

   Was ist neu vs. Pack 3a:
   - Shadow-Tokens auf Drop+Blur umgestellt (moderner Look)
   - Border-Width Standard 4px → 3px
   - Slide-System (Welcome / Sprach-Walze / Dashboard)
   - Brand-Sprechblase als Logo, Sticker-Icons, Ulli-Figur
   - Slot-Maschine: Frame, Walze, klickbare Bedienelemente
   - Hero-Deck + Deck-Pills mit Spielkarten-Stapel-Optik
   - Leitner-Dots, Streak-Banner
   - Bouncy Spring-Animationen

   Legacy-Klassen (.lang-pill, .deck-card, .login__logo, .hero, .hero__art)
   bleiben drin, bis app.js mit Pack 3c/3d umgebaut wird.
