 * analogy-item.css — canonical visual for AnalogyItem.
 * ===========================================================================
 * Single source of truth for .an-eyebrow / .an-stem / .an-stem-a/b/as/blank /
 * .an-choices / .an-choice / .an-letter / .an-choice-main / .an-choice-text /
 * .an-choice-as / .an-elim / state classes. Replaces the per-surface scoped
 * duplicates that previously lived in subjects/vocab/styles.css
 * (.quiz-screen .an-*) and diagnostic-ui.css (.diag-an-region .an-*).
 *
 * Surface stylesheets may still override individual properties for
 * surface-specific behavior:
 *   - .exam-screen (vocab exam mode) flips eyebrow to display:none and uses
 *     box-shadow selected state — kept in subjects/vocab/styles.css.
 *   - .diag-an-region (diagnostic) uses a slightly bigger stem font and
 *     hides elim — kept in diagnostic-ui.css.
 *
 * Loaded BEFORE surface stylesheets in index.html so per-surface overrides
 * win on specificity.
