To be honest, your questions require a lot of analysis and experimenting
even for me, and I am just not very motivated to provide a complete answer
and example. Also, "Image with Mask" and "Video + Mask" require
clarification. Is "mask" just an alpha channel?
In any case, in Kdenlive, pay close attention to the "With Track" option
for a transition. Also, perhaps try to put the "[Video + Mask]" into a
project of its own, and then use it in another Kdenlive project as a
virtual clip. This results in the same thing as nesting <tractor>s when
authoring correct MLT XML except it is uses separate XML files.
Also, if you want to really use CSS, then take a look at WebVfx:
https://www.mltframework.org/bin/view/MLT/WebVfx
I think you could replace the "Image with Mask" and its multiply transition
with a HTML-based WebVfx filter attached to the video clip where the image
is referenced within the HTML instead of MLT XML.
I hope these hints facilitate your further experiments.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
