/*
 * Shared styles for the Bazar Assistant site.
 *
 * Self-contained on purpose: no web fonts, no CDN, no analytics. The whole site is three files
 * and should still work on a slow connection in the market this app is for, which is also why
 * there are no images heavier than the app icon.
 *
 * Colours are the app's own palette, so the site and the thing it is advertising look related.
 * Light values come from apps/android/src/main/res/values/colors.xml, dark from values-night.
