/* ── Large-Field Tournament Strategy Masterclass — scoped page styles ──
   Verbatim port of largefield-styles.css, scoped under body.btf-lf-page.
   Prototype dark-mode variants dropped (the live site is cream-only).
   Short prototype tokens (--forest, --gold, …) are aliased onto the
   shared --th-* palette.

   IMPORTANT: do NOT alias --ink. base.css defines --ink:#1C1814 at root
   and texas-holdem.css maps --th-ink:var(--ink). Re-defining
   --ink:var(--th-ink) would create a cycle (both resolve to empty),
   silently breaking every --th-ink consumer — including the shared
   glossary tooltip background. --ink already resolves correctly at root.

   Sections: hero (funnel) → diffs (4 cards) → variance (funnel + pro
   callout) → stages (3-tab) → focus (3 cards) → cheat (do/don't) →
   summary.
