multiplatform --> mobile, desktop, touchscreen,...
both in terms of graphics as well as chipset portability and device size
reactivity and performance --> from graphics to hardware acceleration
quantify this by comparing with silicon vendor / hw vendor provided original SDK)
BOM / performance --> integrated graphics onto SOC
sub 20 $ hw BOM
benchmark with target portable graphical libraries such as design systems, or us horonix or alternatives
UI design tool / IDE needs to generate production ready code
https://en.wikipedia.org/wiki/Design_system
for reference --> https://material.io/ (micro animations)
flutter is a good solution to use as well as JS
