TYPO3 frontend theme for development purposes: extension development, DDEV
based test instances and acceptance tests.

> [!NOTE]
> This is a development tool, not a production theme. It renders pages,
> navigation and every content element the core registers without depending
> on `fluid_styled_content`, and the public API is not stable and may
> change without a deprecation phase until the first stable release.
