build_wasm.ps1 built the `wasm` STUB preset (PDFENGINE_WITH_PDFIUM=OFF, reflow #ifdef'd out)
and deployed it to the UNUSED pdfengine.{mjs,wasm}. The frontend actually loads
pdfium-engine.{mjs,wasm} (the `wasm-pdfium` preset). So "rebuild the WASM" silently shipped a
reflow-less stub to the wrong file — engine changes never reached the browser.
- Build the `wasm-pdfium` preset (PDFium ON) into pdfeng-build/wasm-pdfium (outside OneDrive).
- Deploy bin/pdfengine.{mjs,wasm} -> public/pdfium-engine.{mjs,wasm} (the rename the frontend expects).
- Set EMSDK_QUIET before sourcing emsdk_env.ps1 (its stderr tripped $ErrorActionPreference='Stop').
- Run a new pdfium-engine.smoke.mjs (buildInfo + live-preview exports) instead of pdfengine.test.mjs,
which targets the stub facade (mock render / engineHasSkia / getDocumentFonts) and can't pass here.
- Relax EAP around the smoke node call so a real failure reports cleanly, not as NativeCommandError.
- pdfengine.test.mjs: de-brittle the buildInfo assertion (was pinned to a stale exact phrase).
Verified: scripts/build_wasm.ps1 runs green end-to-end and deploys pdfium-engine.wasm (md5 53d1ec9f).
