/* ── ADS ──────────────────────────────────────────────────────────────
   Side rails on desktop, exactly ONE banner under the board on phones.
   The rules of this surface, in order of authority:

   1. An ad never overlaps the board. Rails and banner are flow siblings of
      the stage — never positioned over it, never given a positive z-index.
   2. An ad never appears during the reveal/clash beat. `body[data-reveal]`
      (set by timeline.mjs) blanks the whole surface with `visibility`, which
      costs no reflow and keeps the box reserved.
   3. An ad never shifts the layout. Every slot's box is reserved here at
      first paint AND is already full — the house ad ships in the markup, so
      there is no empty hole to fill later and nothing moves when (if) a real
      AdSense unit arrives in its place. CLS contribution: zero, by shape.
   4. An ad never costs a frame. `contain` walls each slot off from the
      board's layout, paint and style, so no third-party DOM inside it can
      reflow or repaint the game. ────────────────────────────────────── */
