/* zodiakk — mobile & responsive layout.
 *
 * Strategy:
 *  - Below 900px: tighten spacing, drop ornamental chrome, stack columns.
 *  - Below 640px (phones): smaller gutters, single column throughout,
 *    hide the fixed hairline frame (too cramped), hide the "meta" clock
 *    cluster in the topbar, stack section heads, stop marquee animations.
 *  - All type sizes scale via clamp() already; we only override when
 *    the clamp floor is still too large for 360–420px viewports.
