/* Cullwise — panel-CMS layout, modernised. Dark skin.
 *
 * Structurally IDENTICAL to the Small Anvil site: same shell, masthead, nav
 * strip, breadcrumbs, sidebar panels, caption bars, row lists. Same class
 * vocabulary. Only the skin differs — change one, consider the other.
 *
 * The palette is the app's "Light Table" system, so the site and the
 * application read as one product. Dark only, on purpose: the app deleted its
 * light palette deliberately, and a bright marketing page in front of a dark
 * application is a bait-and-switch.
 *
 * Gold is what Cullwise thinks. Bone is what the photographer decided. That
 * distinction is load-bearing in the app; it holds here too — gold marks
 * captions and the app's own claims, bone marks the reader's actions.
 *
 * Written from scratch; no PHP-Fusion CSS (it is AGPL).
