/* 24-escalation.css — Phase 8: C escalation modal + toast (items 23+24).
 *
 * Owns:
 *   - .v2-esc-modal             — modal root + backdrop tap = cancel
 *   - .v2-esc-sheet             — content sheet (bottom sheet on mobile)
 *   - .v2-esc-header/title/close — header chrome
 *   - .v2-esc-message           — optional secondary copy
 *   - .v2-esc-actions / .v2-esc-btn — action button row + primary/ghost kinds
 *   - .v2-esc-toast             — small "✓ next level" / "Слово вгадано" toast
 *   - .v2-c-more-context-wrap   — collapsed-by-default wrapper for the extra
 *                                  prev/next strips inside C3 + C4 views.
 *
 * Chip styling + per-view extra strip cosmetics live in 20-c3-view.css
 * (C3 side) and 22-c4-c5.css (C4 side).
 *
 * Loaded from base.html alongside the other v2 component sheets, AFTER
 * the C3/C4 view sheets so modal layering wins.
