/*
 * Dark-first document background.
 *
 * This stylesheet is linked in the head and applies before Angular boots, so
 * it is the only place that can decide what the browser paints first. Without
 * it the document is white until the app renders, which reads as a flash of
 * light theme on every hard load and on the way into sign-in.
 *
 * Marketing, sign-in and admin all render dark, and every rendered surface
 * paints its own background over this, so a light product theme is unaffected:
 * this colour is only ever visible in the moment before anything is drawn.
 *
 * Raw hex on purpose. Theme tokens are defined by the app stylesheet, which
 * has not loaded at this point. It matches the theme-color meta in index.html.
