Linux parts (0L1-4L1 per TASKS_LINUX_WINDOWS.md): - native_bridge: FxGuiServer.cpp HTTP server (Winsock) — /frame BitBlt + PrintWindow fallback -> JPEG (libjpeg-turbo q70), /input PostMessage relay (mouse/wheel/key, coords scaled), /close, /ping; RenderFxJob fxGuiSetup + run_fx_gui_server (offscreen); main.cpp --fx-gui dispatch; vcpkg + CMakeLists WIN32-only + JPEG. - api: open_fx_gui embed flag spawn --fx-gui, parse SF_FXGUI_PORT -> embed_url, fx-gui/close endpoint; 4 unit tests. - ui: VstGuiEmbed component (frame refresh 100ms, ping 2s, input relay, scale coords) shared by MasteringModal + FXRackModal; swap graph<->GUI, cleanup on unmount, dead-bridge toast fallback. - docs: TASKS_LINUX_WINDOWS.md, WALKTHROUGH_WINDOWS.md, PLAN status. Windows tasks 0W1-4W1 remain (build + E2E real VST).
