/**
 * DRI Foundation — Global Giving Map
 *
 * Colours from the Foundation style guide (25 Aug 2026 swatch table).
 * Type is Arial, which the guide names as the default for web.
 *
 * Layout principle after the 27 Aug review: the map is the page. Everything else
 * collapses beneath it, so the map is visible without scrolling and the page is a
 * screen tall at rest rather than seventeen thousand pixels.
