What are you trying to accomplish?

In Catalan (ca), the names of Spain's provinces come straight from CLDR. Three problems make them look broken in a province picker:

• Most names carry a "província de" prefix, which isn't needed to tell them apart.
• The prefix is capitalized inconsistently ("província de Burgos" vs. "Província de Badajoz").
• Three provinces show the ² marker CLDR uses for duplicate names: Illes Balears², Navarra², Cantàbria².

Upstream CLDR still has these names: every Catalan subdivision name is marked draft="provisional", so updating CLDR won't fix it.

What approach did you choose and why?

I added a patch_subdivisions(:ca, ...) block to rake/cldr/patch.rb, the same way we already patch Spanish names (see CLDR-14034) and Portuguese ² names. It rewrites the same 46 province codes as the Spanish patch to their plain names, e.g. província d’Alacant → Alacant, Illes Balears² → Illes Balears.

data/cldr/locales/ca/subdivisions.yml was regenerated by running the new block through the existing patch_subdivisions helper. The helper checks each expected existing value, so every "before" string in the patch matches the data exactly. Only those 46 lines changed.

What should reviewers focus on?

• esc becomes La Corunya. Standard Catalan lowercases the article inside a sentence ("la Corunya"). I capitalized it because it stands alone in a list, matching La Coruña in the Spanish patch.
• The same scope as the Spanish patch: autonomous communities (e.g. esri, La Rioja²) are left alone because they aren't zones of Spain in data/regions/ES.yml.

The impact of these changes

Only Region#full_name(locale: :ca) changes, and only for Spain's provinces. No other locales or countries are affected.

Testing

I added a test that checks no Catalan name for a Spanish zone contains "província" or ². The test fails without the data change.

To try it out:

# bin/console
I18n.available_locales = [:en, :es, :ca]
Worldwide::Config.configure_i18n
Worldwide.region(code: "ES").zones.map { |z| z.full_name(locale: :ca) }

Checklist

• I have added a CHANGELOG entry for this change (or determined that it isn't needed)
