/* Keep — keep.gallery
 *
 * The app's own visual language, on the web. Black ground, white ink, hairlines instead
 * of boxes, and the two hues Keep spends: keepGreen on a keep, favoriteRose on a
 * favourite. Every token below is the one in Keep/Design/Theme.swift.
 *
 * Dark is primary and light is an exact inversion, the same deal the app makes with the
 * system — with one exception: anything drawn as a *device* (the phone, the .mock
 * screens) stays in the app's dark appearance in both, because those are screenshots of
 * an app, not part of the page.
