- Daily Practice (all 31 prepositions) is pinned to the top of the
Prepositions tab once the "Alle Präpositionen" lesson is passed
(>=70% over a full round).
- One-tap mode: after answering, the app flashes right/wrong and
auto-advances. Always on in Daily Practice; a persisted "One-tap"
toggle in the practice header enables it for any other level.
New pseudo-level (id 10.5) that drills all 31 prepositions. App.jsx
pins it to the top of the Prepositions tab once the "Alle
Präpositionen" lesson is completed, and defaults it to one-tap mode.
