/*!
 * Hammhaus Showcase — page-specific styles for index.html (the style guide)
 *
 * Why this file is separate from hammhaus.css: hammhaus.css is the portable
 * product people download; this file is the gallery walls — hero set pieces,
 * playground controls, watermark numerals — that exist only on this page.
 * Keeping them apart means the downloadable system ships zero demo weight.
 * Everything here is scoped to the .sx-* namespace and depends on
 * hammhaus.css for tokens and components. The star is hammhaus.css —
 * these styles are the gallery walls, not the art.
