flex-wrap with fixed-width cards started each new row below the TALLEST card of
the previous row, leaving big gaps under short panels (e.g. the amplifier alone
on a second line). Switch the dashboard to balanced CSS columns (column-width
430px, break-inside-avoid): cards flow top-to-bottom and pack tightly by height.
"Auto" fits as many columns as the window allows; 1-4 cap the column count via
the container max-width. Grip-drag reorder unchanged. Changelog 0.21.1.
