/* WordPress inserts margin-block-start: var(--wp--style--block-gap) between the
   template's top-level sections (header part, main, footer part) — a gap that
   exists even when no markup asks for it. Zero it so sections butt edge-to-edge
   and own their vertical rhythm via padding; this does not affect block gaps
   inside nested layouts. */
