/*
 * Section rhythm copied from Opnar's `.opnar-home`: 0.25rem stacking to
 * 0.5rem at 768px, tied to the layout's own header gap so every page
 * surface breathes at one rhythm.
 *
 * 8px between sections only reads as enough because each block supplies
 * its own separation: `.fv-rail-head` carries a 14px margin under every
 * heading, so the actual gap between one grid and the next heading is
 * 8px, and between that heading and its grid 14px. Opnar's blocks are
 * flat for the same reason — no card chrome, no per-section margins.
 *
 * The page's bottom breathing room comes from `.site-main`, not here.
 */
/*
 * The first block sits at the same rhythm as every other one.
 *
 * `.site-content` carries a 16px top padding site-wide (chrome.css, for the
 * flush header). On this page that lands above the banner as a band three
 * times the gap separating every block below it, so the home page takes its
 * top spacing from `.site-main` alone and the space above the first block
 * equals the space between the rest. Scoped to `body.home` because this
 * stylesheet loads everywhere; the two classes also outrank the single-class
 * rule it is overriding.

 *                  mobile, where a two-card section is still too thin
 *                  to earn its heading
 *   count 3        fills the row on tablet, so it is kept there; hidden
 *                  on desktop where the row is 4-up; trimmed to two on
 *                  mobile so the 2-up row is not left ragged
