Eight tiles across left each one too narrow to read at floor distance. The row
now shows four per page in a 2x2 block, cycling on the same seven-second timer,
so a name is legible from where people actually stand.
The tiles lay the photo beside the name rather than above it. Two rows of
stacked tiles would roughly double the section's height, and the board is
scaled to fit one screen, so height spent here shrinks everything else. The
photo grows to 120px and the name to 26px in the space that buys.
