@decembrya Can you send us the link to https://primariabrasovenilor.ro/ where we can see the example Olivia showed us at the last meeting? We remember cards with a “.” instead of a title, but we can’t find it.

Hi @taitus, the page on https://primariabrasovenilor.ro/ that Olivia showed is nolonger up, but we've set something similar up in our test environment: https://buget.heroesof.tech/despre-bugetare-participativa. See the bottom two cards

@decembrya As usual, we've added a couple of texts in Romanian (a label and a hint for the new field). Could you review them? Thanks! :pray:

The test failure is not related to this pull request; it failed on this version of Consul sometimes.
