 - **Module-level init:** Before `app.ready`, the composition root registers protocols, sets platform flags, constructs all services, and wires dependency injection. `runAndApplyStartupState()` parses CLI args and detects the compositor backend.
 - **Startup:** If `--generate-config` is passed, it writes the template and exits. Otherwise `app-lifecycle.ts` acquires the single-instance lock and registers Electron lifecycle hooks.
 - **Critical-path init:** Once `app.whenReady()` fires, `composeAppReadyRuntime()` runs strict config reload, resolves keybindings, creates the `MpvIpcClient` (which immediately connects and subscribes to 26 properties), and initializes the `RuntimeOptionsManager`, `SubtitleTimingTracker`, and `ImmersionTrackerService`.
-- **Overlay runtime:** `initializeOverlayRuntime()` creates the primary overlay window (interactive Yomitan lookups and subtitle rendering) and registers global shortcuts and bounds tracking via the active window tracker.
-- **Background warmups:** Non-critical services are launched asynchronously: MeCab tokenizer check, Yomitan extension load, JLPT + frequency dictionary prewarm, optional Jellyfin remote session, Discord presence service, and AniList token refresh. Warmup coverage is configurable through `startupWarmups` (including low-power mode that defers all but Yomitan).

 - **Runtime:** Event-driven. mpv property changes, IPC messages, CLI commands, overlay shortcuts, and hot-reload notifications route through runtime handlers/composers. Subtitle text flows through `SubtitlePipeline` (normalize → tokenize → merge), and results are sent to the main overlay renderer and modal surfaces.
-- **Shutdown:** `onWillQuitCleanup` destroys tray + config watcher, unregisters shortcuts, stops WebSocket + texthooker servers, closes the mpv socket + flushes OSD log, stops the window tracker, closes the Yomitan parser window, flushes the immersion tracker (SQLite), stops Jellyfin/Discord services, and cleans Anki/AniList state.
