Thank you @jmontane — great to have Catalan on board, and the translation quality is excellent.

I pushed a small completion commit (250ae14) on top of yours: a new locale also needs an entry in src/lib/og-translations.ts — its keys generate SUPPORTED_LOCALES, which the middleware, sitemap, hreflang alternates and OG images all derive from, so without it /ca is unroutable and the Record<Locale, OgStrings> type check fails the build. I also fixed three accents (desviament, hidrogen, màx.).

This ships in the next release within the hour. Moltes gràcies!
