/*
 * Gallery page hero — US-GAL-01
 *
 * Full-bleed dark band: the image-kit photo sits behind a tinted gradient, and
 * the content is an asymmetric 60/40 split (copy | photo strip), per DESIGN.md.
 * Desktop: 60/40 two column, 2x2 tile grid · Tablet (<=1024px): single column
 * with the strip below the copy, tiles in a 4-up row · Mobile (<=640px):
 * stacked, full-width buttons, 2-up tiles.
 *
 * Every colour / type / spacing value comes from assets/css/design-tokens.css.
 */

/*
 * The site header and nav are styled globally in style.css (.amber-header /
 * .amber-nav). This stylesheet must NOT restyle #masthead or body — an ID
 * selector beats those classes and a bare `body` rule drops the theme's own
 * page background, which would make the header and page look different on the
 * Gallery page than on every other page. Everything below is scoped to this
 * page's own containers.
