 * Playing the Blinds masterclass — page-scoped styles.
 *
 * Loaded only on /poker/strategy/playing-the-blinds/ (gate: btf_is_bd_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 on widget labels.
 *   4. base.css resets `ul,ol{list-style:none}` — re-enable disc bullets
 *      explicitly inside SB-examples lists.
 *   5. `[hidden]` overridden by explicit display:flex — gate with
 *      `:not([hidden])` on callouts.
 *   6. Selection on dark backgrounds → gold highlight.
