- The GPU row's breakpoint could never fire. The settings pane is about
664px at any window size, and the name, three figures, meter and
percentage need more than that, so the one-row layout was dead code.
Each device is now two compact lines: name with the percentage, then
the figures with a fixed-width meter. The name stays readable, the
meter no longer runs the width of the pane, and there is no breakpoint
that cannot be reached.
- The agent, model and quantization grid switched on the viewport, so
between 768px and 1024px it went to three columns inside a 440px pane
and crushed every control. It now keys on the pane and stacks until
the columns genuinely fit.
- Dark mode dropped the palette card's resting border, but that border
is the only focus indicator since the card removes its outline, and an
unlayered rule beats Tailwind's layered focus-visible utility. Keyboard
focus paints the ring colour again.
