/*
 * Gallery chrome.
 *
 * This file used to be deliberately plain, on the theory that a reader copying a
 * demo should copy map code and not page styling. That was the right call for a
 * reference and the wrong one for a showcase: a page that looks like a test
 * fixture tells a visitor the library produces test fixtures. So the chrome now
 * does one job, loudly: it makes the map look published.
 *
 * The rules it follows:
 *
 *   1. The figure is the hero. Chrome recedes to hairlines, space and type.
 *      Nothing gets a heavy border, because a border around a map competes with
 *      the map's own edges.
 *   2. Brand colour lives in the chrome, never in the data. The ApexCharts
 *      accents are for links, focus and the logotype; map fills come from
 *      cartographic ramps. A map coloured in brand colours is decoration.
 *   3. Editorial type for what the map says, interface type for what the reader
 *      operates. Serif titles and a source line under every figure, because that
 *      is the grammar readers already associate with a published map.
 *   4. Still deterministic. Light for everyone rather than following the OS, so a
 *      screenshot, a copied snippet and a bug report describe the same page.
 *      Dark surfaces here are authored, never inherited from a system setting.
