 * Responsive strategy: layout responds to available width, never to browser
 * or device detection. Type and spacing scale fluidly with the viewport via
 * clamp(), and .grid reflows intrinsically, so most of the page adapts with
 * no breakpoints at all. Media queries below handle only the few cases that
 * genuinely need a layout change.
