Thank you for your submission! Everything looks good, but I'll let this PR sit for a bit until there is some more community interest in taking a second look at the translations.

Appreciate your hard work in translating Bluesky!

After fixing Dario's commits I can't see any more issues. Congratulations and thanks for this awesome work!

Talking in voseo form is anachronic, outdated and not recommended in any modern translation style guide.

I rather keep the tuteo form as recommended in all style guides.

About masculine and feminine forms, you're right, is always better to talk in a neutral form, although it's not yet recognized by the Institut d'Estudis Catalans, so, segur, is the correct official form.

That said, it could be replaced by a confirmation, but language needs to be as easy and understanding as possible, so I would go with a simple "Confirmes?, hi estàs d'acord?" For example

Translation is really good. A did some really minor comments. Thanks!

[ivanbea]

Apply suggested corrections from @jordimas @darccio and @mvdan

[ivanbea]

With all the revisions, changes and suggestions made by @darccio @jordimas @mvdan @Mejans and @johnnydement we can consider the catalan localization ready. Thanks to everyone.

[MiquelAdell]

I think the translation is ready with the changes applied

[ferranrego]

Wow! That's an incredible work, thanks @ivanbea for kickstarting the localization in Catalan and the first proposal and to everyone else for dedicating their time.

I can't wait to use Bluesky in Catalan!

Thank you everyone! Merging!

[jordimas]

BTW, if somebody has an invitation code I will love it then I can test the translation too
