/**
 * Answering Questions — widget styles.
 *
 * Sits INSIDE the fleet UniversalContainer card (navy-gray field, blue instruction
 * banner on top, footer at the bottom) — this file styles only the exercise content:
 * the picture (which IS the audio button), the written-sentence slot, the question and
 * the choice cards. Styled like the fleet's other tap-a-choice widgets (Articles /
 * Sentence Builder): white cards, 2px neutral edge, soft shadow, blue hover.
 *
 * STATIC FRAME (§7.1): fixed minimum sizes on the picture, sentence and feedback slots;
 * choices keyed per item so state never ghosts (§6.6); `transition: none` on state-
 * swapped nodes. Every interactive state declared. No !important.
