The offline keepsake viewer had the same two filter defects as the app: typed
suggestions were capped so a matching tag could be unselectable, and the dropdown used
`onmousedown` with a backdrop that swallowed the selection. Rebuilt into
`backend/static/export-viewer/index.html`, which `include_dir!` embeds in the binary.
The eslint ignores were unanchored, so once the export-viewer's dependencies were
installed its nested `.svelte-kit` output was linted as source. Anchored with `**/`.
