product summary cards don't have uniform height

while several product summaries are in the same row, especially products with different statuses and properties, they are terribly unalligned.

i did attach classes to the various elements, most of them static but few of them calculated, so it's stylable in custom.css.

a css artist will highly outperform my css capabilities, but even my idea gives a sensibly uniform result.

my diff is a little intermingled, but i would be glad to explain everything.

thanks in advance,

alex
