- Show full word list before practice starts so students can study words first
- Add per-student young learner mode (set in admin): word stays visible while typing
- Center all practice card content (speak button, prompt, feedback, check button)
- Remove 10-word-per-session cap so large lists (25-30 words) practice all words
- Double the misspelled-word study countdown from 4s to 8s
- Fix word list preview numbering for 10+ items (inline numbers, no clipping)
- Add young_learner column to students table with admin toggle
