/* ── Blackjack variations — scoped page styles ────────────
   /blackjack/variations/, scoped under body.btf-bjv-page.

   Built 2026-10-01 in the style of the rebuilt blackjack guides: a felt hero
   card, paper sections, the rule-by-rule ledger on a tinted band, cards for
   each game's plays, the site table. 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. page.php wraps the
   content in .section-paper, so prose rules carry three classes to outrank
   base.css's `.section-paper > .wrap p:not([class])`.

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