/* ── Mississippi Stud Masterclass — scoped page styles ───────────────
   Verbatim port of msstud-styles.css, scoped under body.btf-ms-page.
   Prototype dark-mode variants dropped (the live site is cream-only).
   Short prototype tokens (--forest, --gold, …) aliased onto --th-*.
   The prototype's <Card> component is replaced by a scoped .btf-ms-card
   glyph.

   IMPORTANT: do NOT alias --ink (it would form a cycle with
   texas-holdem.css's --th-ink:var(--ink) and blank the glossary tooltip).

   NOTE: page-detection helper is btf_is_msstud_page() — btf_is_ms_page()
   is already taken by the micro-stakes page. Block prefix / body class
   `btf-ms-*` / `btf-ms-page` are free (micro uses `mi`).

   Sections: hero (Jacks→paytable) → notpoker (is/isn't cards) → play
   (6 steps + pitfall) → paytable → edge (bars + pitfall) → strategy
   (2-toggle + pro) → similar (4 cards + visible glossary) → summary.
