/* FILL: the card is the screen.
 *
 * Jade, 2026-09-21: "this game should fill the whole screen with the card and
 * the one button that says the word." So: the topbar, the card as big as the
 * viewport allows, one button, nothing else. Same cream as the deck page.
 * Nothing moves when it is tapped: the fill is a clip-path over a picture
 * that is already there, and the button never changes size.
