+- [x] **H1 — Decompose god files.** `SettingsView.tsx` (1104, ~11 cards, ~30 selector subs +
+  ~20 useState), `DownloadBar.tsx` (858, ~17 state hooks), `store/downloads.ts` (614). *Done on
+  `refactor/h1-decompose-god-files`: SettingsView → `components/settings/*.tsx` (one component per
+  card + shared `settingsStyles.ts`), leaving a ~90-line shell (search box + display-toggle filter);
+  each card still renders one `<Card>` DOM node so the filter is unchanged. DownloadBar → a
+  `downloadBar/useDownloadBar.ts` hook (all state + handlers, wrapper handlers keep the
+  preview-invalidation side-effects) + `downloadBar/styles.ts` + `downloadBar/PlaylistPanel.tsx`,
+  leaving a render-only shell. store/downloads.ts → `downloadTypes.ts` (types, re-exported so
+  importers are untouched) + `downloadItem.ts` (buildItem/titleFromUrl/RESOLVING) + `downloadSeed.ts`
+  (preview seed), leaving the store + recordCompletion + wiring. Behaviour unchanged; full
+  typecheck + lint + production build + 248 tests green.*
