/* tenderfoot/css/tf-pip.css - Pip's chat (js/tf-pip.js).
 *
 * The game's own materials (tf-shop.css's stone and gold, tf.css's tokens): a dark plum panel with a
 * gold hairline, Pip's portrait in a gold ring, cream bubbles for Pip and plum ones for the player,
 * a gold "Ask" button. On a computer or tablet it rises from Pip's corner, bottom left, and leaves the
 * rest of the painting in view; on a phone it is a full-screen sheet that stays above the keyboard.
 *
 * SNOOZE MODE (.is-napping): the header goes to night blue, Pip wears his nightcap (pip-sleepy.png)
 * and three z's drift up from him.
 *
 * Every size a finger touches is at least 44 CSS px, every text at least 15 px on a phone
 * (docs/platform-design-spec.md). Everything is under .tf-pip.
