Photos/Files bug: the lightbox download handed nativeSaveFile a bare "/files/<id>" with no name, extension, or mime. Empty mime made bzSaveToPhotos short-circuit as "notmedia" — so saveToAlbum (and its permission prompt) never ran, and the image landed in the generic Files folder as an extension-less blob. Now nativeSaveFile trusts the server's Content-Type when the mime is unknown and appends a real extension (bzExtForMime/bzEnsureExt), so images reach the Images folder AND Photos. File preview: replace the @capacitor/share "share sheet" open with a new native FileOpener plugin (QLPreviewController). bzOpenFile now prefers a real Quick Look preview and only falls back to the share sheet if the plugin isn't in the build. Wired file-opener into mobile/package.json and the codemagic SPM diagnostics loop. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

// Previews an already-downloaded file with iOS Quick Look — the native "look at this file" surface: swipe,

// WHY A PLUGIN: the app loads its UI from a REMOTE origin (remote.bizgaze.com), so it cannot open a local
|
|
// file:// URL in the WebView (cross-origin / capacitor local-serving isn't on this origin). @capacitor/share
|
|
// only offers the share SHEET ("open in another app"), not a preview. Only QLPreviewController, presented
|
|
// from native code, gives a real in-app preview. Quick Look picks the renderer from the file extension, which
|
|
// is why the web layer now saves downloads with a correct extension (see bzEnsureExt in home.html).
