/* LazyMouse website.
 *
 * The same instrument plate as the apps: flat paper, black ink, hairline rules,
 * square corners, and one vermilion that means "the link is live". The top strip
 * is the status strip from the desktop app, and it does the same job here: its
 * fill reports the link state of the demo below it.
 *
 * Scene: someone on a laptop, deciding in half a minute whether this is a real
 * tool. So the page is built around things that can be touched (a pad that moves
 * a cursor, gestures that play, a modifier that cycles), each with a readout that
 * says what just happened, and a plain statement of what is and is not finished.
 *
 * Contrast against paper: ink 15:1, muted 7.6:1. Vermilion is never text on
 * paper (2.9:1); ink sits on top of it (6.4:1).
