/*
 * MeowTarot — Phase 5 B1: Full Reading (Celtic Cross) selection board
 * css/full.css
 * ─────────────────────────────────────────────────────────────────────────
 *
 * Rebuild of the Phase 4 "deal-board + arrange-list" 2-stage UX into a
 * single 12-card grid that aligns with the Daily + Ask boards. User
 * picks 10 cards in order; the result page auto-assigns positions
 * (1st → The Situation, 2nd → Crossing, … 10th → Outcome) via
 * js/full-reading-position-order.js.
 *
 * Mirrors the css/daily.css layout pattern (topbar, title hero,
 * shuffle button, 4-col grid, counter, CTA) scoped to data-page='full'.
 *
 * REQUIRES: css/theme-tokens.css (--mt-* namespace).
 * LOAD ORDER: LAST. After css/phase-3-redesign.css.
 *
 * SECTIONS:
 *   §1  Page background + shell layout (mirror daily-shell-active)
 *   §2  Top bar (deck name + streak chip)
 *   §3  Board title hero (h1 + th + hint)
 *   §4  Shuffle button row
 *   §5  Card-board grid override (4-col, 12 slots)
 *   §6  Card slot states (unselected / selected / dim / disabled)
 *   §7  Counter
 *   §8  Continue CTA row
