 - **2026-10-12 (gap 6, #1319, #1305, #1324):** Editing an XFA form keeps a radio item's stored text when it contains a space, so a later layout still selects it. Replace Pages on a split selection replaces those pages and leaves the gap; editing the dialog range still replaces the span. Marking a figure decorative rewrites only that figure's content stream, so a header, added text and unknown stream entries stay. Estimates unchanged.
 - **2026-10-15 (M14, gap 24):** `misc.localization` and `misc.installers` move from planned to partial. Localization: 22 catalogs ship, but Chinese shows tofu in releases, Telugu has no release font and Arabic is not mirrored. Installers: macOS and Windows releases are signed, Linux packages are not. The Acrobat menu diff itself remains open. Estimates unchanged.
 - **2026-10-15 (M14, PNG export):** Export ▸ Image as PNG, `pdfcraft-cli render` and the `page_render` automation/MCP tool write an opaque page as RGB at deflate level 3 instead of RGBA at the default level 6: the files stay the same size and are written 3–5× faster (a 300-dpi scan drawn at 220 dpi: 805 → 167 ms; a text page at 220 dpi: 70 → 40 ms; an annual-report page at 150 dpi: 179 → 64 ms). A page with translucent pixels is still written as RGBA. The automation tools use the engine's encoder instead of a copy of it. Estimates unchanged.
+- **2026-10-15 (G14, Romanian localization):** Added Romanian (`ro`, Română) as an interface and date language with a 2,673-entry catalog covering every bundled key, and a CLDR plural rule (`plural_ro`: one / few / other, "20 de pagini"). Locale tags `ro` / `ro-RO` / `ro_RO.UTF-8` / `ro-MD` resolve, so Auto picks it on Romanian Windows. Coverage and plural tests added. Status `partial` like the other catalogs (no translated help).
 - **2026-10-13 (G14, Vietnamese localization):** Added Vietnamese (`vi`, Tiếng Việt) as an interface and date language with a 2,591-entry catalog (`plural_none`) covering 100% of the current localizable key union (plus `theme`/`Appearance`). Locale tags `vi` / `vi-VN` / `vi_VN.UTF-8` resolve; calendar months use numeric `Tháng 1`…`12` / `tháng 1`…`12`. Native-speaker community review recorded. The twelve-language localization mean moves from ≈59% to ≈68%; weighted readiness ≈49% → ≈50%. Status stays `partial`: engine/OS details, document contents, filenames, CLI/MCP and external help stay outside the catalog by design.
 
 - **2026-10-13 (M3, typed zoom):** The right rail's zoom percentage is an editable field: type 150, 150% or 62.5 % and press Enter, Escape discards, and nonsense keeps the current zoom. The control channel's zoom option shares its parser, which now refuses zero, negative and non-finite values.

 Displayed keyboard shortcuts use the same active interface language. For example, German shows `Strg+K` and `Strg+Umschalt+S` in the toolbar, menus, command palette, tooltips and Keyboard shortcuts dialog; macOS keeps its modifier symbols (`⌘`, `⇧`, `⌃`). Key names have their own `key` catalog context, so the Delete key can read `Entf` while the command remains `Löschen`. A missing key-name entry falls back to the English key name. Actual bindings and machine-facing command ids remain stable.

A system language without a catalog shows English. On Windows, **Auto** uses the Windows display languages, in preference order, when no supported locale is selected by those environment variables. Neutral `C`/`POSIX` locale values (including `C.UTF-8`) inherited from a launcher do not override the Windows display language; explicitly named supported locales such as `fr_FR.UTF-8` still do. The query asks Windows directly (`GetUserPreferredUILanguages`, through the `sys-locale` crate) without starting a process, and is cached for the process. If detection fails or the display language has no catalog, PdfCraft shows English.

-Dialogs, panels, menus, notices and history labels go through the catalog (`tl!`). Most shipped catalogs (Japanese, Chinese, Russian, Bulgarian, German, Spanish, French, Telugu, Hungarian, Ukrainian, Italian, Brazilian Portuguese, Arabic, Slovenian, Kazakh, Polish, Greek, Turkish, Lithuanian, Vietnamese and others) cover the current localizable surface (about 2,000–2,600 entries each), and Czech (2,674 entries) covers the same surface. Untranslated labels use English. Error details that come from the engine or the operating system are shown as they are, inside a translated frame ("操作「…」に失敗しました: …"). The command palette matches the translated label, the English label and the command id. Vertical Japanese PDF rendering is an existing viewer feature; this change does not add vertical text editing. Document contents, filenames, CLI/MCP/control protocol strings and external help stay outside the catalog. Per-language coverage, script support and what each language still needs are in [localization-parity.md](localization-parity.md).

 Whole sentences that the layers below word — what the accessibility checker found, what the PDF/A verifier reports, what a signature's details say, what is wrong with the pages to print, what an edit is called in the history — are translated too, because those layers hand the sentence over apart from the document's own words.

 The Catalan catalog has 2,592 entries, written from the meaning of the English labels in standard Catalan computing vocabulary. Commands use the second-person imperative (`Desa`, `Obre`, `Cancel·la`) and notices use impersonal or informal wording. Catalan has two plural forms like English (1 is singular; 0 and every other count take the plural: `1 pàgina`, `3 pàgines`). Every `ca-*` locale, including Valencian (`ca_ES@valencia`), uses this catalog. The interpunct of `l·l` is U+00B7, which the bundled Latin faces cover (tested in `tests/fonts.rs`). The date picker has Catalan month and weekday names; dates are day-first like French (`dddd d mmmm yyyy`), but after a day the month carries its own preposition, elided before a vowel (`7 de març`, `7 d'abril`, `8 d'octubre`), as Czech and Russian change theirs through `months_with_day`; the year takes `\de` from the pattern (`d mmmm \de yyyy`). A native Catalan speaker (the contributor) has reviewed the translation.
 
+The Romanian catalog (`ro`, Română) has 2,673 entries and three plural forms (`plural_ro`, CLDR `ro`): `one` for 1, `few` for 0 and counts whose last two digits are 1–19 ("2 pagini", "101 pagini"), `other` for the rest, written with "de" ("20 de pagini"). Commands use the noun form common in Romanian software ("Salvare", "Deschidere…"); messages address the user formally. Redaction is "Anonimizare" ("redactare" means editing in Romanian), a watermark "Filigran". Calendar month names are lowercase inside dates (`{day} {month} {y}`). The bundled Inter faces cover ă, â, î, ș, ț (comma below). Coverage tests require every bundled key. Not yet reviewed by a second native speaker; status `partial`: no translated help, and engine/OS details stay English inside a translated frame.

 Edit text reads Hebrew lines in typing order and writes them back in drawing order (`crates/edit/src/bidi.rs`); letters the page's own font lacks are drawn with the craft-fonts `Hebr` face (Noto Sans Hebrew) as Type 3 glyphs, and a build without one says so. Hebrew points (niqqud) can't be written yet in Edit text. Add text (#128) draws Hebrew with the same face through the shaped path Arabic and Thai use: right to left with numbers and Latin in place, points kept on their letter, and typing order for copy and search. The craft-fonts revision pinned for CI and releases has no `Hebr` face yet, so until one is added releases report that error instead of drawing the missing letters, and refuse Hebrew in Add text.
 
 Japanese interface text uses BIZ UDPGothic from [craft-fonts](https://github.com/storytold/craft-fonts), an optional build input that every release includes (`CRAFT_FONTS_DIR`; see the README). A build made without it has no Japanese face, so Japanese labels show replacement boxes. Chinese is drawn with the same craft-fonts CJK faces (in Simplified Chinese the `Hans` faces come first, so a line never mixes faces with different baselines), so a character none of them has shows a replacement box (and every Chinese character does in a build without craft-fonts). Russian, Bulgarian, Czech, Brazilian Portuguese, German, Spanish, French, Hungarian, Italian, Turkish, Lithuanian and Albanian need only the bundled Latin faces (tested in `tests/fonts.rs`). Hungarian uses the same one/other plural rule as English: 1 is singular, and every other count — including 0 — is the other form. After a numeral the noun stays singular (`1 oldal`, `2 oldal`). Telugu is drawn with a craft-fonts `Telu` face (Noto Sans Telugu, kept in the web build too), whose conjuncts egui shapes; a build without one shows Telugu labels as replacement boxes, and the release-pinned craft-fonts input has no Telugu face yet.
