/* =============================================================
   Schlaf-Quest · Schieberegler-Modal
   - Bottom-Sheet im Stil der uebrigen Quest-Modals (modals.css)
   - Der native <input type=range> IST das sichtbare Bedienelement:
     Zonen-Verlauf als Track, weisser Knopf als Thumb -> ueberall
     auf dem Balken greifbar (kein separater Deko-Thumb mehr).
   - Farb-/Radius-/Font-Tokens aus app.css, damit es zum Rest passt.
   Logik: openSleepModal()/onSleepInput() in app/main.js,
   XP-Kurve in quest/sleep.js.
