/*
 * reading-overlay.css — styles for js/reading-overlay.js and js/reading-deeplink.js.
 * Lane cc-impl-1, 2026-10-10. Flag: reading_overlay_enabled (the modules add no
 * element while it is off, so nothing here matches).
 *
 * Everything is prefixed .rdg- and nothing here restyles a .pmv- element.
 * The viewer chrome is dark by default and light under html.light, like
 * css/plan-markup-viewer.css; the chrome colours below follow it through the
 * --rdg-* variables. The layer colours sit on a white drawing sheet in BOTH themes,
 * so they are chosen for white paper and do not change with the theme.
