/*
 * FIX: On mobile (≤768px), CSS :hover transforms cause iOS click failures.
 * When a card or button moves on :hover (touchstart → ":hover" applied →
 * transform kicks in), the click event fires at the original touch coords
 * while the element has visually shifted — causing misses.
 *
 * We use max-width:768px (not "hover:none") because the hover media query
 * is unreliable: tablets, Samsung DeX, and some Android browsers report
 * hover:hover even without a mouse.
 *
 * ALSO: overflow:hidden + position:relative on .giveaway-card requires
 * cursor:pointer on iOS Safari for child click events to fire correctly.
