The card track was 28rem, which fits four across a full-width page but only
three once the sidebar takes its 250px - and 1920 with the sidebar is the
common case here, so the board showed three. The track is 22rem now, with an
explicit four-column cap above 96rem: left to auto-fit alone a wide screen
reaches five, and a fifth column only makes the cards narrower until the rows
they hold start truncating again.
Measured at 1366, 1600, 1920 and 2560: three, four, four, four.
The floor-plan preview drops from 500x385 to 390x300. At the old size it
covered the row it was launched from, which is the row you are trying to read.
