/*
 * The public face of Aben To Go.
 *
 * Palette lifted from the app (src/theme/colors.ts) rather than invented, so
 * someone who has used the app recognises the site as the same thing. Ochre
 * is the brand colour; rust is reserved for the one destructive action, the
 * same rule the app follows.
 *
 * No web fonts and no external stylesheets. Partly speed, mostly principle:
 * a page whose job is to explain what happens to your data should not open a
 * connection to a third party to render itself.
