- Add new sample manifest with fulltext and associated files
- Add API routes for locally handling annotation lists and annotations
- Update invalid files for testing

Upgrade to Vue 3 with Vite as build tool. Components keep the old options API, while the composition API is used in imported modules. Looks and functionality remain unchanged.

- Replace mixins with modules, using named imports
- Rename files and lint everything according to the latest Vue coding style
- Update all packages to their latest version, except OpenSeadragon
- Use Vitest instead of Jest for unit tests (Vue recommendation)
- Remove the last remnants of support for Internet Explorer
- Improve HTML templates
- Rewrite and extend tests

The actual error message is different on each browser, so make the test more generic.

We actually want version 3.0.0, not 3.1.0, which introduced a small but annoying bug.

- Remove obsolete setLoading function
- Rename readOptionsFromUrlQuery to initOptions to clarify that this function does more than the old name suggested

This led to a hard-to-reproduce issue when loading a collection and a manifest at the same time via a slow connection.

Such a tiny bug, yet so hard to track down 🤦

- Enable display of multiple error messages
- Add ARIA attribute

- Allow configuration of the local IIIF server port so multiple servers can run at the same time
- Extend collections tests to check if multiple child manifests can be loaded successively
- Add basic tests for TIFY's API

Update all packages to their latest minor version (except OpenSeadragon), remove unused packages.

And add a manifest URL input.

Use ResizeObserver instead of an event handler. Not only does this make the code more concise, but also reacts to changes of the element size when the window size stays the same.

- Add close-all button
- Improve styling

- Replace instance-dependent modules with globally available plugins to restore multi-instance functionality
- Move all functions from main to App for better testability
- Fix text flashing in fulltext panel
- Fix translations in help panel
- Improve coding style
- Improve unit tests

Although invalid IIIF, there are collection manifests in the wild with missing labels, and we don’t want them to make TIFY crash.

Update all dependencies to their latest minor version, except OpenSeadragon.

Remove obsolete packages:
- sass
- vitest-canvas-mock
