/* The "How it works" page that opens once after install (preview: three
 * versions, start-a/b/c.html). Loaded after styles.css, ui.css and home.css,
 * so it has the homepage's look: near-black, Geist, the typed mono headline
 * with its green caret, paper-coloured buttons and green for live state.
 *
 * The demo (js/start.js) is drawn at one fixed size, 760 by 460, and scaled
 * to its box, so it looks the same at every width: a Chrome window with a
 * Google Doc, and the HumDocs popup hanging from its toolbar icon.
