Prepares the v0.7.0 release.

Highlights

• url accepts a Blob (e.g. a File from an <input type="file"> or a drop event) holding a zipped OME-Zarr file, in the options object, the constructor, OMEZarrTileSource.open and loadOMEZarr; it is read with the zarrita ZipFileStore.fromBlob store
• zip defaults to true for a Blob; zip: false is rejected synchronously by the constructor and by loadOMEZarr, since a single file can only be a zipped OME-Zarr
• New blob property holding the configured Blob; tileSource.url stays a string and is an object URL created once per Blob instance (resolveUrl accepts a Blob), so tile sources for the same Blob compare equal and share cached tiles
• OpenSeadragon only routes strings and plain objects through supports, so a File must be wrapped as { type: "ome-zarr", url: file } or passed to the constructor rather than given to the viewer directly (documented in the README)
• colors getter returns undefined (rendered as white) for omero channel colors that are not six-digit hex strings, instead of colors with NaN components
• Example page shows a file picker for a zipped OME-Zarr file when the url query parameter is missing (demo only, not part of the published package)

The full list is in the changelog.

Release

• package.json bumped to 0.7.0, changelog rolled over to [0.7.0] - 2026-09-17
• Tag v0.7.0 still needs to be pushed after merging to trigger the publish workflow

Checks

pnpm run lint, fmt:check, test (no test files) and build:lib pass. Verified end-to-end in Node (jsdom) against a synthetic zipped OME-Zarr wrapped in a File: loading, zip: false rejection, shared object URL and equals, tile rendering, and the inline-configuration path through a real OpenSeadragon viewer; the existing URL path renders unchanged.
