## Letterpress English and Spanish word lists

The accepted-guess dictionaries in
`lib/games/word-puzzle-dictionary-en.ts` and
`lib/games/word-puzzle-dictionary-es.ts` are modified, filtered derivatives of
the Letterpress Word List by Loren Brichter:
https://github.com/lorenbrichter/Words

Source files `Words/en.txt` and `Words/es.txt` are pinned at commit
`f4976d6a6d34beb431dec8d4b443a138f4dc8bee`. Their canonical source SHA-256
digests are, respectively,
`b78af5ad2f66bed4e64fd48334af7d5620a91c45e7a578c084b9b72f9abcd5dd` and
`a6e805ab9a56a32e27aa528c2abf022e6594d8dc6001322236560a7a58ee34b4`.
The generator normalizes entries to NFC, keeps lowercase entries containing
exactly five `a-z` letters for English or `a-z` plus `ñ` for Spanish, removes
duplicates, uppercases them, and sorts the output.

## LibreOffice Russian Hunspell dictionary

The accepted-guess dictionary in
`lib/games/slovo-za-slovo-dictionary.ts` is a modified, filtered derivative of
[`LibreOffice/dictionaries`](https://github.com/LibreOffice/dictionaries),
source file `ru_RU/ru_RU.dic` at commit
`32b006a2c22a4ac7e8ed3f03346f7b3d85a970a4` (canonical source SHA-256
`f6047416a0204adbecf3a451b874ec8a97ee37e2cbc714466ef04d8dbcc0d6fc`).
Hunspell flags and non-lowercase entries are removed, and the remaining words
are normalized and filtered to exactly five Russian letters.
