City HUD at 320-375 px: top bar and buttons crowd each other

At 320 px the four stat tiles, the exit button, the music mini player (title cut to 'Lens to Pie...') and the radar all stack in the top 230 px, and the UNIVERSITY and WALK buttons float over the scene with no grouping.

Under 380 px: collapse the stat tiles to one line (mode + speed), shrink the radar to 96 px, move the music mini player into a single round button that opens the player sheet, and group UNIVERSITY/WATCH/WALK into the Hyper controller column.
