 ### Launcher + Plugin Runtimes
 
 - `launcher/main.ts` dispatches commands through `launcher/commands/*` and shared config readers in `launcher/config/*`. It handles mpv startup, app passthrough, Jellyfin helper commands, and playback handoff.
-- `plugin/subminer/init.lua` runs inside mpv and loads modular Lua files: `main.lua` (orchestration), `bootstrap.lua` (startup), `lifecycle.lua` (connect/disconnect), `process.lua` (process management), `state.lua` (shared state), `messages.lua` (IPC), `hover.lua` (hover-token highlight rendering), `ui.lua` (OSD rendering), `options.lua` (config), `environment.lua` (detection), `log.lua` (logging), `binary.lua` (path resolution), `aniskip.lua` + `aniskip_match.lua` (intro-skip UX).

AniSkip intro detection lives in the SubMiner app (`src/main/runtime/aniskip-runtime.ts`), which drives mpv chapters and the skip key over the IPC socket.
