Deck content, one YAML file per deck, organised by language code.
A deck may be a core and its layers. The core holds the language learnt; each
layer holds one native language's meanings, notes and labels. Every deck is on
its language's path, <lang>-path.yaml, which lists the decks in teaching order.
The full guide is in the wiki:

- Romanising Indic languages: how readings are written for each language.
- Deck licences and quoted books: the licence terms, and quoting books, songs and films.
- Deck format: the format summary; the full file is docs/DECK-FORMAT.md.
