 * "Install app" — the controls, the steps sheet (js/install.js) and the /install/ page.
 *
 * Loaded by every page that can be installed from: the welcome screen, the concierge, /install/
 * and both manager pages. Every rule is under an `av-install` class, so nothing here reaches into a
 * page's own styles, and every colour is one of the nine brand colours (Accent is the only action
 * colour). Type is inherited from the page, so Bengali and Devanagari keep each page's own faces.
 *
 * Touch targets are 44px. Focus is a visible 2px ring. Motion is one short rise of the sheet, and
 * none at all under `prefers-reduced-motion`.
