Six buttons need 188px but the small card's text column bottoms out near
160 (its 180px column less padding), so the reset button — the only one
that is conditional, hence the only one anyone noticed — hung outside the
card by up to 15px. The buttons go tighter there (154px), and the row can
wrap as a backstop rather than clip. AddToPlaylist and DownloadButton now
take the button style as a prop so all six stay one size.
Tile actions also pin to the tile's bottom edge, so they land in the same
place whether the title above ran to one line or three.
