/* read-aloud.css — the "Listen" player (static/js/read-aloud.js).
 *
 * A bento card above the reading: Listen/Pause, a paragraph slider, Stop
 * and speed. While it plays and its own place has scrolled away it
 * docks as a pill at the bottom centre of the window. The paragraph being
 * read gets a soft green wash and the word being spoken a slightly deeper
 * one, both drawn without moving a single line of text.
 *
 * Buttons keep buttons.css's rule: black text, a light fill, a coloured
 * edge. Every control is at least 44px.
