/* ClearNote — clearnote.app
 *
 * One stylesheet. No framework, no webfont, no third-party request of any kind — the privacy
 * page says the site has none, and that has to stay true.
 *
 * The display face is `ui-serif`, which is New York on Apple platforms and Georgia elsewhere.
 * ClearNote's readers are, by definition, Mac and iPhone users, so the typography they see is
 * a real editorial serif that costs nothing to load. Body text stays in the system sans, which
 * is what the app itself uses.
