Language & theme
Switch the UI between BG / EN and dark / light.
Language (BG ↔ EN)
In the header there's a globe icon with a dropdown — pick Bulgarian or English. The change is instant and saved in a cookie for next visits.
This is the UI language, not the bot's. The bot auto-detects the client's language (BG, EN, DE, RU and 8 more) and replies in the same.
Theme (dark ↔ light)
Next to the globe there's a Sun/Moon button. Click to toggle. Dark is the default — the whole site is optimized for dark theme. Light works everywhere, but if you spot a contrast issue — let us know.
Persistence across sessions
Both settings are stored in a cookie on the device. On a different computer you'll see defaults (auto-detect from browser locale + dark theme). Logged-in accounts don't sync preferences across devices yet.
