/* ──────────────────────────────────────────────────────────────────────────
 * ABC Poker masterclass — page-scoped styles.
 *
 * Loaded only on /poker/strategy/abc-poker/ (gate: btf_is_ab_page()).
 * Sits on top of texas-holdem.css; reuses --th-* tokens.
 *
 * Cascade gotchas pre-baked (learned across builds):
 *   1. `.prose` chains beat `:not([class])` selectors in base.css.
 *   2. `body.btf-th-page .prose p { margin: 0 }` strips paragraph margins.
 *   3. Eyebrow ::before dash suppressed where eyebrow is a widget label.
 *   4. base.css resets `ul,ol{list-style:none}` globally — re-enable
 *      disc bullets explicitly inside pillar do/don't lists.
 *   5. `[hidden]` overridden by explicit display:flex — gate via
 *      `:not([hidden])` on callouts.
 *   6. Selection on dark backgrounds → gold highlight.
