- New UI catalogs `crates/ui-egui/locales/fr.toml`, `de.toml` and `pt-BR.toml`: every UI string (1,351 keys, 36 with plural forms), every command label (519) and every main-menu wording (29) translated, 1,899 entries each. Machine-drafted from our English, marked `status = "draft - needs native review"` like Spanish, so Preferences shows the draft note. Placeholders are identical to English; `|context` keys are translated per context (sizing "Fill", stroke "Join", glass "Light", open comments).
- Language conventions: French uses no-break spaces (` `) before `: ; ? !`, inside guillemets and before `%`; German uses formal address and German quotes; Brazilian Portuguese uses Brazilian vocabulary (arquivo, salvar, tela, voce).
- Not added to `COMPLETE`: that list forces every later PR to translate new strings into each complete language, so the three drafts are registered as incomplete and fall back to English per key; Spanish stays the only enforced language. `docs/translating.md` says so and how to list what a draft lacks.
- Plurals: `plural_one` now takes 0 as singular for French and Brazilian Portuguese (CLDR integer rules); English, Spanish and German stay `n == 1`.
- Language choice: Preferences > Language lists Francais, Deutsch and Portugues (Brasil) by their own names (from the catalogs). System now walks the OS's preferred-language list and takes the first language with a catalog: Windows' full `GlobalizationPreferences.Languages`, all of macOS's `AppleLanguages`, gettext's `LANGUAGE` then the locale variables on Linux/BSD; the browser still uses `navigator.language`. A tag with only a regional catalog reads it (`pt-PT`, `pt` -> `pt-BR`). `pref.language` docs list `fr|de|pt-BR`.
- Overflow (German is the longest): `widgets::dropdown` now keeps its label on one line, ending it with an ellipsis and showing it in full on hover (it used to wrap mid-word, e.g. the auto layout sizing and stacking dropdowns); `elided_dropdown` merged into it. Two-column sublabels in the right panel and the home screen's cards elide the same way. English is unchanged.
- Docs: localization-parity (languages, string counts, status, hours), translating, target-app-parity, ROADMAP, gaps (gap 5), roadmap (current focus 4), mcp. Localization 20% -> 30%, 45-75 h -> 40-65 h; ready for real work stays ~52%; full parity ~289-564 h -> ~284-554 h; beta ~170-305 h -> ~162-292 h.
