 * The parent theme's global styles add a margin-block-start between every
 * top-level block inside a flow/constrained layout (WordPress's default
 * block gap). Our page sections already size their own vertical rhythm via
 * padding, so that extra margin only shows up as a stray gap in the page
 * background whenever two adjacent sections use different background
 * colors. Every custom section pattern renders as a <section>, so reset the
 * gap for that tag specifically without touching normal group blocks.
