/* ==========================================================================
   S14-8 — Book Landing Page
   ==========================================================================
   Conversion-optimized single-book layout used when `mbs_landing_page_mode`
   is enabled for a PRO book. All rules scoped to `.mbs-landing-wrapper`.
   Tested on GeneratePress and Divi at 320 / 768 / 1440 px.
   Dark mode uses :is(.mbs-dark-mode, [data-mbs-theme="dark"]) & pattern
   (ancestor-selector nesting) — equivalent to the prior flat dual-selector.
