 * Implied Odds masterclass — page-scoped styles.
 *
 * Loaded only on /poker/strategy/implied-odds/ (gate: btf_is_io_page() in
 * functions.php). Sits on top of texas-holdem.css; reuses --th-* tokens.
 *
 * Cascade gotchas baked in from minute one (learned from the BR/OD/PF
 * builds):
 *   1. base.css `.section-paper > .wrap p:not([class])` wins over a
 *      plain `body.btf-io-page ... p` rule. Use `.prose` chains.
 *   2. `body.btf-th-page .prose p { margin: 0 }` strips paragraph
 *      margins. Restore via .prose chain where needed.
 *   3. `.btf-th-eyebrow` is `display: flex` with a `::before` brass
 *      dash. Don't override `display` — it stacks the dash above text.
 *   4. `.btf-th-display` is `margin: 0 0 .4em` — spacing owned by the
 *      eyebrow's `margin-bottom`.
 *   5. UA `[hidden] { display: none }` is overridden by explicit
 *      `display: flex / inline-flex`. Add `button[hidden] { display: none }`
 *      where needed.
 *   6. Selection on dark backgrounds → gold highlight.
 *   7. Hero CTAs use site-standard `.btn-primary` / `.btn-ghost`.
 *   8. Inline labels in widget halves get their `::before` dash
 *      suppressed.
