/*
 * First paint before the bundle runs (QA 2026-09-26 O-27): on a slow connection index.html used to
 * be an empty <div id="root">, so the screen stayed white for 5+ seconds — white even for a dark
 * theme visitor. This is a static shell in the document itself: the map's own background, the
 * brand mark and a "yükleniyor" line. It lives inside #root, so React's first render replaces it.
 *
 * Standalone from src/styles: those load with the bundle. Colours mirror theme.css (--map-bg,
 * --solid, --acc), keyed off the data-theme /theme-init.js sets before paint. No inline style, so
 * the CSP can stay at style-src 'self'.
