Work from `/home/lucas/Android-app/DailyPiece`. Follow TDD where noted. Plain git, simple commit messages (ignore any global \"Lore\" format). Every new source file starts with a one-line Korean header comment. Keep each file under 300 lines.\n\n## Reference: Capacitor LocalNotifications (v8.2.0) — IMPORTANT\nThis app has NO bundler — the `www/js/*.js` files are plain ES modules loaded directly in the browser/WebView. So you CANNOT `import { LocalNotifications } from '@capacitor/local-notifications'` (that needs a bundler). Instead, access the plugin via the global Capacitor bridge that Capacitor injects into the native WebView at runtime:\n```js\nconst LN = (window.Capacitor && window.Capacitor.Plugins && window.Capacitor.Plugins.LocalNotifications) || null;\n// On web (no Capacitor) LN is null → no-op gracefully.\n```\nThe plugin API (call on LN):\n```js\nawait LN.requestPermissions(); // returns { display: 'granted' | 'denied' | 'prompt' }\nawait LN.cancel({ notifications: [{ id: 1 }] });\nawait LN.schedule({ notifications: [{\n id: 1,\n title: '하루조각 🧚',\n body: '오늘 조각 맞췄어? 조각이가 기다리고 있어!',\n schedule: { on: { hour: H, minute: M }, repeats: true, allowWhileIdle: true },\n}]});\n```\n`schedule.on` with `repeats:true` fires daily at that hour/minute.\n\n## What to build\n\n### 1. Dependency\n- `cd app && npm install @capacitor/local-notifications@^8.2.0` (adds to package.json dependencies). Network is available.\n\n### 2. `app/www/js/settings.js` (NEW, TDD)\nPersists user prefs in localStorage key `dailypiece.settings`.\n- `export function loadSettings()` → returns object merged over defaults `{ notifyEnabled: true, notifyHour: 21, notifyMinute: 0 }`. Handle missing/corrupt JSON → defaults.\n- `export function saveSettings(partial)` → merges partial into current and persists; returns the merged object.\n- Keep it pure (uses bare `localStorage` global, like the existing `storage.js`).\n\n### 3. `app/test/settings.test.js` (NEW, TDD — write FIRST, confirm fail, then implement #2)\nUse the same MemStorage shim pattern as `app/test/storage.test.js` (inject `globalThis.localStorage`, dynamic `await import`). Tests:\n- loadSettings with empty storage → returns defaults (notifyEnabled true, notifyHour 21, notifyMinute 0).\n- saveSettings({notifyHour: 8}) then loadSettings → notifyHour 8, other defaults intact.\n- saveSettings({notifyEnabled:false}) persists false.\nRun: `cd app && node --test test/settings.test.js` → must pass.\n\n### 4. `app/www/js/notify.js` (NEW)\n- `export async function applyNotificationSchedule()`:\n - `const LN = window.Capacitor?.Plugins?.LocalNotifications; if (!LN) return { ok:false, reason:'unsupported' };`\n - load settings. Always `cancel` id 1 first.\n - if `notifyEnabled` is false → return `{ ok:true, scheduled:false }`.\n - `requestPermissions()`; if display !== 'granted' → return `{ ok:false, reason:'denied' }`.\n - schedule the daily notification (id 1) at notifyHour:notifyMinute as shown above. Return `{ ok:true, scheduled:true }`.\n - Wrap plugin calls in try/catch; on error return `{ ok:false, reason:'error' }` (don't throw).\n\n### 5. `app/www/index.html` (MODIFY)\n- Add a settings gear button in the header. The header currently has a left group (🧚 + 하루조각 h1) and a right `#fairy-status` div. Add a `` (style to match: e.g. `class=\"text-2xl ml-2 active:scale-90\"`), placed next to `#fairy-status` (wrap them so both fit).\n- Add a hidden settings modal at the end of the `.max-w-md` container (sibling of `
