What

DeckCraft currently has no way to print at all — no file.print command (only file.export, which always writes to a path), and no Print entry anywhere in the UI, not even behind a shortcut.

This adds a print path that goes straight to the browser's native print dialog instead of forcing a download first:

• Services::print, a web-only hook (PDF bytes in, system print dialog out), alongside the existing download hook
• SlideApp::print_now(), which builds the PDF via the engine's cmd::file::pdf_bytes (the same lowest-level function file.export already uses under the hood) and hands the bytes to the hook
• Ctrl/Cmd+P wired up in ui_shortcut — doesn't collide with the existing Ctrl+Shift+P command palette shortcut
• a "Print…" entry in the File menu, right after "Export…"
• the web runner's print service implementation: PDF bytes → Blob → object URL → hidden <iframe> → iframe.contentWindow().print() once the iframe has finished loading

Why

Export-only means every print is a round trip through the OS's file picker and PDF viewer just to get to a print dialog. This skips straight to it, the same way Word/Excel/PowerPoint's own Ctrl+P does.

Mirrors the same feature already added to WordCraft (storytold/wordcraft#209) and GridCraft (storytold/gridcraft#143).

Testing

Built with trunk build --release, deployed, and smoke-tested in Firefox: Ctrl+P and File → Print… both open the system print dialog on the current presentation's PDF.

Pushed a second commit here: a File tab + full backstage panel (New/Open/Save/Print/Export/About), filled with PowerPoint's red, mirroring WordCraft's blue backstage (storytold/wordcraft#209) and the matching one just added to GridCraft (storytold/gridcraft#143). DeckCraft had no File-tab equivalent at all before this, so it seemed natural to land alongside the print feature rather than as a separate PR, since Print is one of its pages.

Pushed one more commit: an interface-language system with Serbian, both scripts (sr Cyrillic, sr-latn Latin) — same pairing as storytold/wordcraft#250 and the matching addition to storytold/gridcraft#143.

DeckCraft had zero localization before this. Translation happens at a few high-leverage points rather than at each of the hundreds of call sites: the shared ribbon widgets (big_button, icon_toggle, color_grid, section, drop_button, etc.) translate their own label/tip internally, and dialogs.rs's title() (every dialog window title goes through this one match statement), buttons(), field() and check() do the same — so every existing and future caller picks up translation for free. DeckCraft attaches tooltips via .on_hover_text(...) chained onto the Response rather than as a widget parameter (unlike GridCraft), so the 19 call sites doing that are wrapped individually. Title bar, ribbon tab names and the File backstage are translated directly, and the backstage gets a new Options page with the language picker.

216 strings, clean-room translated, then mechanically transliterated into Cyrillic. 11 tests, including one that checks actual font bytes — DeckCraft's own fonts only embed real files with CRAFT_FONTS_DIR set at build time (not available here), so I verified egui's own default font (Ubuntu-Light) genuinely has the Cyrillic and Serbian Latin (š č ć ž đ) glyphs used, rather than assuming.

Scope, stated plainly: ribbon, dialog titles/fields/buttons, File backstage. A few dialog bodies (table/chart data editors, the SmartArt picker, the equation editor) draw bespoke UI outside the shared helpers and aren't covered yet — a string without a translation just shows in English, so more coverage can land incrementally.

This PR conflicts with main (Cargo.lock, web.rs, backstage.rs, dialogs.rs, lib.rs, ribbon.rs, widgets.rs and more), so this review covers the diff and the commit list only. Nothing was built; I did not run a web build or a browser.

The branch has three commits, and the title and description cover only the first:

1. web: print straight to the system print dialog, not just export: the print_pdf hidden-iframe helper in deckcraft-web.
2. ui: File backstage (New/Open/Save/Print/Export), PowerPoint red: adds a 165-line crates/ui-egui/src/backstage.rs with its own page list and APP_COLOR.
3. i18n: add an interface language system, with Serbian (sr, sr-latn): a catalog parser, sys-locale and ttf-parser dependencies, Serbian catalogs, and tl! wrapping across the dialogs and menus.

What I found against current main:

• Main already has a full crates/ui-egui/src/backstage.rs (with a print module, print scope/range/layout options and the Export page), so commit 2 is an add/add conflict that would replace it with a much smaller page. The description's "no Print entry anywhere in the UI" no longer matches main.
• On the web, main's SlideApp::print_pdf (app/files.rs) builds the PDF and downloads it when there is no pick_save. So the one thing in commit 1 that main lacks is the hand-off to the browser's print dialog; I did not find Services::print or print_now on main.
• Commit 3 adds an interface-language framework. Main has none (dialogs/language.rs is the proofing language), but other open PRs add one too (i18n: add Russian, Spanish, French, Portuguese and German interfaces #110, i18n(ja): Japanese menus, ribbon and status bar (first step) #1119), so these overlap and will conflict with each other.

On the web print code itself: it builds a Blob and object URL, appends a hidden display:none iframe, sets onload before src, and calls contentWindow.print(). It never removes the iframe or revokes the URL, which the comment says is deliberate, so each print leaves one iframe and blob for the life of the page. The description reports a Firefox test only. I did not test other browsers; printing a PDF from a display:none iframe is, from what I know, not reliable in every browser, so it is worth checking in Chrome/Edge and Safari.

Suggestion: split commit 1 into its own PR rebased on main, wired into print_pdf's web branch, and drop commits 2 and 3 from this one.
