v0.5.2 — Mobile layout fix

On a phone the cards were wider than the screen and clipped on the right, and the performance tiles collapsed to a single column.

.panel is a CSS grid, and grid items default to min-width: auto — so the wide nowrap tables grew their cards past the grid track. .scroll's overflow-x never got a chance to contain them, and the root's overflow-x: hidden clipped the excess silently, so it looked like missing content rather than a layout bug.

Every grid and flex container now lets its children shrink below content width. Tables scroll inside their cards as intended and the tiles get their two columns back.
