/* Casilla reference presentation. Owned by the casilla reference surface.
 *
 * The generated per-modelo pages (dev/docs/casilla_reference.py) are where a
 * search result lands, and there is no per-casilla prose to lean on, so each
 * entry is ranked by the question a filer actually has: what box is this, how
 * does it get filled, and what backs it.
 *
 * The ranking is carried by TYPE, not by containers. An earlier pass gave the
 * fill statement its own bordered panel and gave every fact a pill; the panel
 * fought the card it sat in and the pills flattened signal against noise. Here
 * one card is one box; inside it weight and colour do the ordering, and a pill
 * is reserved for a fact that is genuinely exceptional (required, a bounded
 * range, a segmento, absent from the official form).
 *
 * Tokens come from the Furo skeleton (--color-*) and the Cadrumo theme layer
 * (--cadrumo-radius-*), so light and dark both track the site.
