Thanks for the first pull request here. CI needs a maintainer to approve the run before it starts, so it may sit for a bit before anything happens. pytest tests/ -q passing is the main thing I look at.

Thanks for picking this up. Two things, and the second one is on me for not spotting it when I wrote #519:

1. All ten locale files were re-serialized. The diff is 2358 added lines for what should be about ten, because every one-line object was expanded onto several lines. #519 asks for the JSON to be edited by hand for exactly this reason: it makes the real change impossible to review and conflicts with every other open translation PR. Please reset the locale files to main and add only what is needed.

2. Most of these strings are already translated. The keys exist in all ten locales and simply were never wired up:

Literal	Existing key
Disposable email detected	results.emailrep.disposableWarn
Domain is spoofable (missing SPF/DMARC)	results.emailrep.spoofableWarn
Free email provider	results.emailrep.freeProvider
Catch-all server (accepts any address)	results.smtp.catchAllWarn

So those four lines should use i18n('results.emailrep.disposableWarn') and so on, with no new keys. The existing values already include the ⚠, so drop the symbol from the JSX for those three. Right now the new results.email.* keys hold English text in every locale, so the Russian interface would still show English.

Only "No breaches found" needs a new key. results.breaches.none fits next to the others; please give it real translations, at least for the languages you can check, and the English text for the rest.

@NovaCode37 Fixed the locale files formatting by reverting them to main and appending only the new results.breaches.none key. Also wired up the existing results.emailrep.* and results.smtp.* keys in ScanResults.tsx as suggested, which meant removing the redundant warning symbols from the JSX.

Thanks, this is what I asked for. I pushed one small commit to keep pl.json in its multi-line style.
