Hi! I'd like to work on this issue. Can I be assigned?

Hi! I’ve added an initial Hindi (hi) translation and confirmed that the language selector is working.

For now, I translated only around 5–6 strings that were already marked for translation, just to keep the change small and easy to review.

While doing this, I noticed that some text in the templates is not wrapped with {% trans %} or {% blocktranslate %}, so those lines don’t show up in the .po file and don’t get translated yet.

Before opening the PR, I wanted to ask:

Is it okay if this PR only includes translations for already marked strings, and the missing translation tags are handled in a separate PR?

Is translating only a small subset of strings fine, or would you prefer more complete coverage for one language?

Is adding just one language (Hindi) enough for this PR, or should more languages be included?

Hi! Hindi and French seem to be already supported. I’d like to add Spanish translations if that works for the project. Please let me know if this language is suitable. Thanks!
