/* Hallmark · pre-emit critique: P5 H5 E5 S5 R5 V5
 * Hallmark · genre: editorial · macrostructure: Catalogue · theme: Grid
 * enrichment: none (las piezas vivas SON la imagen) · nav: N9 · footer: Ft4
 * tone: manual de sistemas · anchor hue: ultramarino 264
 *
 * contrast: pass (40-41) — muted 5.35:1, accent 7.59:1, mezclas sobre placa >= 4.56:1
 * slop: pass (42-45) · honest: pass (46) · chrome: pass (47) · tokens: pass (48)
 * responsive: pass (49) · mobile: pass (34, 49, 50-57) — 320/375/414/768/1280/1920
 * gate 23: la placa inunda una banda entera de tinta señal. Es la excepcion que
 * el tema Grid prescribe ("at most one per page, and every page should want one"),
 * no una fuga del acento: fuera de ella el ultramarino no pasa del 2%.
