vite-plugin-obfuscator processes ALL output chunks including vendor libraries, corrupting Mapbox GL's WebGL shader string literals via base64 encoding and string splitting. This caused the map to render as a blank screen in production. Vite's built-in esbuild minification already mangles identifiers and removes whitespace, providing sufficient code protection. Adds regression tests to prevent re-introducing obfuscation plugins.
