/* snapdrive — Mini App styling.
 *
 * Two themes, ours, and light is the one it opens on. This reverses what was
 * here before, where every colour came from the client's --tg-theme-*
 * variables: it meant the app had as many appearances as Telegram has themes,
 * and on a desktop client with a custom one the archive came out in colours
 * nobody had ever looked at. A gallery is mostly other people's photographs,
 * and they are judged against the surface behind them, so that surface has to
 * be a decision rather than an inheritance.
 *
 * The viewer still chooses: the switch is in the profile, and the choice is
 * remembered. What is gone is Telegram choosing for them.
