// The Logcat visual map is PROPRIETARY. Wails embeds the compiled frontend JS into
// the release binary (//go:embed all:frontend/dist), so without this the map's logic
// would ship in readable form. We obfuscate ONLY the map files (engine + renderers),
// and only in production builds (`apply: 'build'`, so `wails dev` stays debuggable).
// Settings are deliberately moderate: NO control-flow-flattening / self-defending
// (would wreck the 60fps render loop) and NO transformObjectKeys (the GraphConfig
// object is accessed across files — renaming its keys would break the app). What we
// DO get: local identifiers renamed + every string literal encoded into a base64
// string-array, so the algorithms aren't human-readable in the shipped bundle.
