/* ============================================================
       KIDVERSE READER v4 — Full-Width Cinematic Layout
       Key changes from v3:
         • Hero: full-width, 420px tall, edge-to-edge, no side gaps
         • Layout: no max-width cap on outer shell — fills screen
         • Content area: max-width 1280px centered, sidebar left-fixed
         • Sidebar: 240px, stuck to left, tighter cards
         • Story area: gets all remaining space (no artificial limit)
         • Side padding removed so story reads edge-to-edge on large screens
    ============================================================ */
