/*
 * Page hero, in the site's vocabulary (blocks: opener cover, chapter wide):
 *   photograph  framed within the chrome container under the white header,
 *               a low landscape (about 1376 x 500 px on desktop), no shade
 *   panel       engraved burgundy, the fading gold frame from its upper
 *               right; anchored 64 px in from the photograph's left edge,
 *               rising over its lower part and hanging 80 px below it onto
 *               the white, so the hero opens and closes on white
 *   words       the path in small gold capitals (current page underlined),
 *               the heading in the white serif, the standfirst in rose
 * Phones: the photograph, then the panel overlapping its foot.
