Sit the below-card Adorn label flush with the card's bottom edge

A 1px overlap into the card still read as the tag riding slightly too high.
Anchor the flipped-below label's top edge exactly at the card's bottom edge
(zero overlap) instead; its z-index keeps it above the selection outline
stroke, so it still reads as attached. Verified live (label top == card
bottom).
