/* MarkHippo — app.css
 *
 * The editor's chrome: header, split pane, status bar, dialogs. The rendered
 * document's own styles are in preview.css.
 *
 * One stylesheet, two themes, in the shape JsonHippo and Rest Hippo use: the
 * dark theme is the Hippo family palette (the one hippoherd.com uses), the
 * light theme its daylight counterpart. The theme follows the system unless
 * the header toggle pins one. These values are the Hippo palette's, the
 * defaults for the first paint; the palette in use — Hippo, a plugin's, or
 * the user's own — is set on <html> as custom properties by
 * js/theme-manager.js (and, before the first paint, js/theme.js), and the
 * Themes dialog edits them.
 *
 * The brand orange (#E06000, hue 25.7 — the logo's own, src/img/markhippo.svg)
 * is used as a fill: the white hippo on it is 3.59:1. Text in the accent
 * uses --accent, the same hue deepened for light (#A84800, 5.85:1 on white,
 * 4.96:1 on the palest surface) and brightened for dark (#FF9A52, 8.11:1 on
 * #1c1c1c), so it passes AA on both.
 *
 * Naming: mh- prefix; state classes are block--modifier.
