Take the renderer's 6.13.0, and keep the call its readme now gets wrong

[andiwand]

@opendocument/odr-core 6.12.0 → 6.13.0.

Nothing new to call

The JavaScript surface did not move. Against the two tarballs, index.js, odr-core.mjs and index.d.ts are byte-identical, and loading both and comparing enums and fileTypes() gives no difference — no new formats, no new HtmlConfig option, no new binding. So there is no feature here to adopt; the version bump is the adoption.

What we get anyway

The wasm grew ~184 KB, and the change is in what it renders. Diffing the html for public/sample.odt between the two:

• Type stops being scaled twice on a phone. The rendered page now probes whether the engine honours text-size-adjust under a css zoom, and where it does, restates the zoom as a percentage so a paged document's text holds the box it was fitted to. Also applied under @media print.
• Table cells start at the top. td{vertical-align:top} — Word and ODF put a cell's content at its top where the browser default centres it.

Both arrive just by opening a document. Nothing on this side opts in.

The readme regression

The only other change in the package is its README, and it changed to something untrue:

-doc.edit(JSON.stringify(iframe.contentWindow.odr.generateDiff()));
+// `generateDiff()` returns the json already; stringifying it again is a string
+// where `edit` wants an object, and it throws.
+doc.edit(iframe.contentWindow.odr.generateDiff());

That is backwards. edit binds to a std::string, so the object is what throws — checked by driving both versions directly:

	6.12.0	6.13.0
edit(JSON.stringify(diff))	applies, saves	applies, saves
edit(diff)	BindingError: Cannot pass non-string to std::string	BindingError: Cannot pass non-string to std::string

index.d.ts agrees with the behaviour, not the readme: edit(diff: string).

saveDocument already passes a string and is correct, so the code does not change — but it now carries a comment saying why, because someone reading that readme will otherwise come here and "fix" it, and that breaks saving an edited document. Worth reporting upstream.

Verified

• npm run build and astro check clean (0 errors/warnings/hints).
• scripts/sync-odr.mjs emits public/odr/6.13.0/ and the forwarder points at it; the version reaches the bundle via __ODR_VERSION__.
• Against the built and served site, not the tarball: sample.odt opens and renders, and a diff in the exact shape viewer.ts sends applies, saves, and the edit is still there when the saved bytes are reopened. No console errors.
• Restored the "license": "MPL-2.0" line npm dropped from the lock entry — registry metadata for a package published hours ago, the license is unchanged in both.
