How it works

The webkit bundle (webkit/index.tsx) runs inside the Steam community browser and injects the CSStats.gg button with a small vanilla-DOM function (csstatsInjectMain in webkit/inject.ts). Settings are stored by a small Lua backend (backend/main.lua) and edited from the plugin's settings panel in the Steam client.

The backend resolves its own directory via Millennium's utils Lua module (utils.get_backend_path()) and reads/writes settings with utils.read_file / utils.write_file.

Plugin Database review note: The store review forbids CDP injection machinery, raw window.MILLENNIUM_API access, and custom-styled settings UI (divs/buttons/badges). The plugin uses webkit-only injection, imports everything from @steambrew/client / @steambrew/webkit, and uses Steam native components (ToggleField) for the settings panel.
