WP Scripts follows specific naming conventions: style.scss becomes style-index.css, editor.scss becomes index.css. Both SCSS files must be imported in index.js for the build system to discover and process them.
The build pipeline transforms SCSS to CSS and handles asset versioning automatically. Always run development builds when modifying assets to see changes and catch configuration errors early.
WordPress loads the built block.json file, not the source version, so all asset paths reference files in the build directory. This separation allows for build-time transformations and optimizations.
