/* ── Betting systems — scoped page styles ─────────────────
   /blackjack/strategy/betting-systems/, scoped under body.btf-bsys-page.

   Rebuilt 2026-09-26 from the betting-systems mock (seo-research/
   blackjack-betting-systems): a felt hero card that stakes one sequence two
   ways, the seven system rules as a ruled list, the sequence explorer with
   its ledger, the settlement card and the ten-session record. Hero chrome
   shared with texas-holdem.css; serif for headings and display figures,
   Outfit for body and component text, mono for eyebrows and micro-labels.

   NOTE: do NOT alias --ink (circular with texas-holdem's --th-ink).
