+ * Source of truth is assets/hero-source.png (1672×941). It is committed so

+ * change the source or the numbers here and re-run.
+ *
+ * TWO CROPS, ON PURPOSE
+ * ---------------------
+ * The hero slot is not one shape. On desktop the artwork sits behind the whole
+ * panel at roughly 2.1:1 → 2.7:1; below the one-column breakpoint it collapses
+ * to a band between 2.6:1 and 4.9:1. A single file under `object-fit: cover`
+ * centre-crops, which at the extremes slices a strip through the middle of the
+ * scene and loses the schoolhouse — the same failure the previous SVG hero had.
+ *
+ * So:
+ *   wide  the full frame, including the empty cream area the artwork reserves
+ *         on the left for the headline. Used behind the desktop panel.
+ *   band  a crop around the schoolhouse and the path, already near 2.6:1, so
+ *         the narrow band barely crops it at all. The school sits at ~65%
+ *         across, which is why the CSS pairs this with object-position: 65%:
+ *         squeezing further toward 4.9:1 crops the empty sides, not the subject.
+ *
+ * AVIF and WebP are both emitted. This is flat-shaded vector-style artwork, so
+ * AVIF lands roughly an order of magnitude under the source PNG; the JPEG is
+ * only the <img> fallback and is never served to a current browser.
