I have tested this item ✅ successfully on a1a738b

I got all cassiopeia css files back but
I had to remove line 27 in /build/build-modules-js/update.js to allow
npm install
to work.

fsExtra.copySync(Path.join(rootPath, 'libraries/vendor/maximebf/debugbar/src/DebugBar/Resources'), Path.join(rootPath, 'media/vendor/debugbar'));

Not sure if it is the right way though.

How do I know when & where I apply the fix or update?

[ghazal]

Check this:
J4.x:Setting Up Your Local Environment - Joomla! Documentation
https://docs.joomla.org/Special:MyLanguage/J4.x:Setting_Up_Your_Local_Environment
and this:
JavaScript Tests for Joomla4 - Joomla! Documentation
https://docs.joomla.org/JavaScript_Tests_for_Joomla4

Even though, in my opinion, these tuts should be revised.

"Docs" is a Wiki, so anyone can contribute, revise ;-)

[ghazal]

Yes. Indeed.
But my knowledge of CLI, NPM, Composer, etc ... is barely sufficient to get me through the procedure. I have more questions than answers.

So what specific question do you have :) here to help!
