🐛 Bugfixes

• PDF tekst-rendering — gestripte tekst (.HOGHU shift) — fonts met ontbrekende /CIDToGIDMap werden niet correct als Identity geïnterpreteerd, waardoor karakters door systeem-Arial werden vertaald als Unicode-codepoints. CID 46 (K in embedded ArialMT) → Unicode 46 = . → -29 shift. Fix in open-pdf-render/src/fonts.rs: missende /CIDToGIDMap → Identity per ISO 32000-1 spec, géén systeem-font fallback voor Type0/CID, en ToUnicode-CMap-fallback chain. Geverifieerd op AutoCAD/PDF X-Change PDFs.
• Embedded Type1 fonts (UniviaPro, Calibri Light, etc.) — werden eerder volledig genegeerd door de vector renderer, waardoor tekst onzichtbaar bleef in Word/InDesign exports. Nu geparseerd via hayro-font crate (eexec decryptie + charstring decoder), zodat de echte letterformen renderen i.p.v. een Arial-substitutie.
• Linux / Ubuntu:
  • "Open with → Open PDF Studio" werkt nu vanuit Nautilus/Files (file-association in tauri.conf.json toegevoegd).
  • Printers selecteren werkt op Linux + macOS via CUPS (lpstat -p); cups-bsd toegevoegd aan .deb dependencies.
• Windows installer: WebView2Loader.dll wordt nu gegarandeerd meegebundeld via een pre-bundle workflow-stap in CI (faalde stilletjes voor v1.47.5).

⚡ Performance

• Thumbnails 108× sneller — de processor was 3 seconden gepauzeerd bij elke renderPage (auto-resume timer zonder early-resume signaal). Time-to-all-thumbnails op 4-pagina vector-PDF: 2810 ms → 26 ms. Pause-window verlaagd naar 500 ms + expliciete resumeThumbnails() na de actieve render.
• Achtergrond vector-prefetch bij doc-open — alle pagina's krijgen extract_draw_commands op een achtergrondworker gedraaid (concurrency 2, yieldt tussen pagina's). Thumbnails hitten daarna allemaal het JS replay-pad → tekst-only pagina's tonen tekst i.p.v. alleen page-background.

🧹 Onderhoud

• 394 regels dood code verwijderd: ongebruikte MuPDF WASM helpers in renderer.js + verweesd tile-renderer.js (300 regels, 0 importers).
• renderer.js van 1458 → 1394 regels.

Since v1.47.5

🐛 Bug fixes

• Garbled PDF text (.HOGHU shift) — fonts with missing /CIDToGIDMap were not interpreted as Identity per spec, causing characters to be translated through the system Arial cmap as Unicode codepoints. CID 46 (K in embedded ArialMT) → Unicode 46 = . → -29 shift. Fixed in open-pdf-render/src/fonts.rs: missing /CIDToGIDMap → Identity per ISO 32000-1, no system-font fallback for Type0/CID fonts, and a ToUnicode-CMap fallback chain. Verified on AutoCAD / PDF X-Change re-saved PDFs.
• Embedded Type1 fonts (UniviaPro, Calibri Light, etc.) — were silently dropped by the vector renderer, leaving text invisible in Word/InDesign exports. Now parsed via the hayro-font crate (eexec decryption + charstring decoder), so the original letterforms render rather than an Arial substitute.
• Linux / Ubuntu:
  • "Open with → Open PDF Studio" now works from Nautilus/Files (added fileAssociations for application/pdf in tauri.conf.json).
  • Printer selection works on Linux + macOS via CUPS (lpstat -p); cups-bsd added to .deb dependencies.
• Windows installer: WebView2Loader.dll is now guaranteed to ship via a pre-bundle workflow step in CI (was silently missing in v1.47.5).

⚡ Performance

• Thumbnails 108× faster — the processor was paused for 3 seconds on every renderPage (auto-resume timer with no early-resume signal). Time-to-all-thumbnails on a 4-page vector PDF: 2810 ms → 26 ms. Pause window lowered to 500 ms + explicit resumeThumbnails() call after the active render.
• Background vector prefetch on document open — all pages get extract_draw_commands run on a background worker (concurrency 2, yields between pages). Thumbnails subsequently all hit the JS replay path → text-only pages render text instead of just the page background.

🧹 Cleanup

• Removed 394 lines of dead code: unused MuPDF WASM helpers in renderer.js + orphaned tile-renderer.js (300 lines, 0 importers).
• renderer.js shrunk from 1458 → 1394 lines.
