/* Ehu kids games, shared look (v2). PRD §12: calm, big targets (≥96 px), rounded type.
   Layout concept: a painted storybook scene fills the screen; soft white "toy" cards and glassy
   controls sit on top; Ehu stands in the bottom-left corner and reacts in a short speech bubble;
   the question always lives in one card at the top, with a replay button. */
