I just wanted to share an update: not only is the user interface translated into Russian, but the course generation itself is also fully localized and available in Russian.

Hey, thanks for putting this together!

Since this PR was opened, we've refactored the i18n system. Adding a new locale now only needs two changes:

1. A lib/i18n/locales/<locale>.json file with all translation keys
2. One line in lib/i18n/locales.ts to register it

See the Translation Guide and #365 (Japanese) for reference.

Could you rebase onto current main and simplify your PR to follow this pattern? The translation strings you've already done are great, it's mainly the wiring that needs updating. Happy to merge once it's aligned.
