 * Ding Dong — the public website.

 * The palette is the app's own, taken from Utilities/HexColor.swift rather
 * than approximated: DDback #FFFDF7, DDink #0B1A26, DDblue #0075C2. Somebody
 * who taps "Privacy Policy" in Settings should land somewhere that plainly
 * belongs to the same product, because a legal page that looks like a
 * different company reads as one, and these pages exist to be believed.
 *
 * Everything here is deliberately one stylesheet with no build step, no
 * framework and no web fonts. These pages are served by Caddy's file_server
 * straight off disk, and the whole point of a policy page is that it loads on
 * a bad connection on somebody's phone.
