The 320px source images were being downscaled ~9:1 by CSS to fit the
36px display size -- old WebKit's naive scaler handles that ratio
badly (visible aliasing on TouchPad). Pre-scaling to 72x72 (2x the
36px CSS size) cuts that to a clean 2:1 ratio while keeping a crisp
@2x source for modern high-DPI screens.
Answering a question collapses it to a one-line green summary with a
"Change" link; the next question/instructions animate in below. This
is the checkpoint to compare against the "always-visible options,
grows downward" experiment (State B).
