View Transitions: Use the new attr() or match-element for the view-transition-name ?

A comparison of two CSS approaches for assigning view-transition-name values: the advanced attr() function and the newer match-element keyword. While both work for same-document view transitions, match-element has two key limitations — it doesn't work across MPA (multi-page app) navigations because element identity differs between documents, and it can't be used to uniquely target specific elements in ::view-transition-*() selectors. The attr() approach is more flexible when either of those scenarios applies.
