/* Client Proofing gallery - a deliberately separate visual system (own
 * palette + type pairing) from the rest of the site, scoped entirely to
 * page-proofing.php (this file is enqueued only when that template is
 * active). Carried over from the original standalone prototype largely
 * as-is; the only structural change is renaming its .grid class to
 * .proofing-grid, since the sitewide layout.css already defines its own
 * unrelated .grid utility (loaded on every page) - keeping the original
 * name would have silently collided with it.
