Merge Crowdin changes per key so translations from PR #531 are retained without dropping localization keys added on main. Normalize locale filenames for Flutter, keep incomplete languages behind the 70% production threshold, and retain them in Crowdin for continued translation.
Merge origin/l10n_main (PR #428) with a per-key three-way resolution:
Crowdin values win only where main did not change the key since the
last sync, so the unused-key removal, store->repo wording sweep, and
ICU plural fixes survive. Korean is restored at 98% completion and
mapped again in crowdin.yml and both language pickers; ar/hi/nl/zh-CN/
zh-TW stay dropped (37% and below).
The es/pt/zh base locales still shipped the old Store labels, the
backup-restore hint said 'from the store' in every locale (boutique
in fr, store loanword in ko), and the Go store lookup error said
'not found in store'. All user-visible surfaces now say repo;
translator descriptions in the template updated to match.
1,303 stale entries dropped across 19 locales (largest groups:
Spotify credentials flow, collection playlists, notification
channels, backup strings); generated localizations rebuilt.
Crowdin sources need a resync after this lands.
Three-way per-key merge: Crowdin wins for keys it updated, locally
added keys that Crowdin has not exported yet are kept. Also normalizes
@@locale to underscore form (es_ES, pt_PT, zh_CN, zh_TW) and repairs
two translations whose placeholders diverged from the template
(ar extensionsInstallPartialSuccess, es_ES cueSplitSplitting).
Add localization keys for verification browser settings, manual
verification help dialog actions, and lossless conversion dithering and
resampler option labels.
Add English template strings and Indonesian translations for playback,
audio conversion, library settings, metadata actions, store snackbars,
SongLink region names, and other previously hardcoded user-facing text.
Regenerate AppLocalizations from the updated ARB files.
Add a localized description header and Material 3 styling (rounded
corners, scrollable layout, surface color) to the album folder structure
picker in Files settings.
Back up the store registry URL plus each installed extension (id, version, enabled flag and settings) and restore them on a new device by reinstalling from the store and re-applying settings. Secret-flagged settings (tokens/API keys) are excluded by default behind an opt-in 'Include extension credentials' toggle. Device-bound signed sessions are never backed up. Settings are merged on restore so omitted secrets are not wiped; failed reinstalls are reported.
Add a Backup & Restore page that exports app settings, download history, liked tracks, wishlist, playlists (with cover images) and favorite artists into a single JSON file, and restores them on another device. Settings restore preserves device-specific storage location (SAF tree URI, download dir). Includes EN strings and ID translations.
