Every renderer module that persists state was wrapping its localStorage.getItem/setItem/removeItem call in the same try/catch idiom — handling private-browsing quirks and other sandbox contexts where storage isn't writable. Three identical patterns repeated nine times across renderer-streamers (filter / sort / hide-downloaded state), renderer-updates (skipped-update version), and renderer.ts (active-tab persistence).
Introduced three helpers in renderer-shared.ts:
- safeLocalStorageGet(key, fallback = '') — wraps getItem with the try/catch + fallback
- safeLocalStorageSet(key, value) — wraps setItem
- safeLocalStorageRemove(key) — wraps removeItem (needed for clearSkippedUpdateVersion which actually deletes the entry rather than blanking it)
Refactored 9 callsites. Reduces the noise:before:
try { return localStorage.getItem(KEY) ?? ''; } catch { return ''; }
try { localStorage.setItem(KEY, value); } catch { /* localStorage may be unavailable */ }
after:
return safeLocalStorageGet(KEY);
safeLocalStorageSet(KEY, value);
Left the VOD scroll-positions persistence in renderer-streamers untouched — its surrounding try/catch wraps JSON.parse/stringify logic that doesn't fit the simple helper signature.
