To apply multiple CSS styles, either: +1. Combine them into a single file/string before loading, or +2. Use a different CSS provider instance for each style section. + +For better maintainability, CSS should be stored in separate files in the `src/platform/css/` directory with corresponding `.css.h` header files for fallback embedded CSS. + +The project includes a CSS syntax verification script (`scripts/verify_css.py`) that runs during CI to catch potential syntax errors that could cause crashes or layout issues.
