   SAVE STATUS — Pill (global) + Trail (pro Quest)
   Zwei Layer Feedback fuer "kommt der Tap wirklich am Server an":
   - .save-pill   floats unter der Topbar, zeigt Pending/Saved/Errors
   - .save-trail  spawned body-level am Check-Button, 3-Punkte-Phase
   Beide leben ausserhalb von #page-content, damit DOM-Re-Renders
   der Quest-Liste sie nicht killen.
