[GerganaKremenska]

BREAKING CHANGE: titleText, subtitleText, status, headerInteractive properties, action and avatar slot and header-click event are move to component, and the card now has a header slot, instead of all the properties.

The card markup needs to be fixed in -
http://localhost:8081/test-resources/pages/Timeline.html
http://localhost:8080/test-resources/pages/Carousel.html
http://localhost:8080/test-resources/pages/Components.html
http://localhost:8080/test-resources/pages/Kitchen.html
http://localhost:8080/test-resources/pages/Kitchen.openui5.html

Add mention of ui5-card-header in docs/Public Module Imports.md and package/main/README.md

All the indentations in the files you've edited have been converted to spaces. So you need to format them back to tabs.

Looks good, there are some inline comments, that you can find.

One thing, that I noticed, not sure if we need to address it.

If a header slot is used with a custom header, not the CardHeader, the separator line between the header and content parts is not displayed (probably it's part of the CardHeader).

Did you already discuss this internally? Should we draw this line, or let the application developers add it to the custom header (which might be not so convenient as they should now the CSS param for the color of the line)? I will accept any decision from your side.
