 * Rounding is a different job, and still ours. `clampSize` bounds without
 * rounding, so a fractional stored value survives hydration and reaches the
 * panel, storage and `aria-valuenow` unchanged until the next drag. Every other
 * way a width enters the app is already integral; this is the one entry point
 * reading a value the app cannot vouch for.
