Measured on the owner's screenshot rather than estimated: the artwork and
meta rows span 366 px, the seek and transport rows 368. Qt draws a
Rectangle's border INSIDE its bounds, so the card's visible fill is already
1 px in on each side — but the footer was anchored to the card's outer edges
and painted straight over the hairline, so the outline stopped exactly where
the footer began. Micro looked right because there the footer IS the card and
there are no two layers to misalign.
Inset by the border width on the three edges it touches, with its corner
radius reduced to match so the curve nests inside the card's instead of
racing it. No gap opens above it: the surface area still ends at the old
boundary, so the two now overlap by a pixel rather than parting.
