All of this is still alpha. The app is usable for development testing and personal
validation, not stable public study use. Review decks exist for multiple modules, but
content quality is still being corrected.

Formatting polish continues
Dutch
Dutch Chapters 1-25 are available and the curriculum has been revised. Most content is already acceptable, so Dutch will be the first test for Reading-format normalization. A possible minor Chapter 18 issue will be reviewed once it is specified.

Next major content milestone
Standardize and polish the Reading layer, beginning with Dutch and then applying the
resulting format to Vietnamese. Reading is the authoritative source; Decks are already
largely derived from it, while Grammar and Exercises will follow later. The reader will
also eventually let learners show or hide translations.
