/* Sizing follows the touch-target guidance both platform vendors publish: 44px
 * minimum (Apple HIG), 48px preferred (Material). `min-height` rather than a
 * fixed height so a label that wraps grows the button instead of spilling out
 * of it. Horizontal padding is roughly twice the font size, which is the
 * conventional ratio for a button that reads as pressable rather than cramped. */
