/* The skip link is the phone's only way past the game. The third pass gave it 44x44 geometry and left
   it off-screen, so it existed for keyboards and nothing else — a screenshot at 390px showed the reader a
   clipped fragment of the game's own footer instead. So: on a narrow screen it is a real, visible,
   thumb-sized control placed BELOW the game panel, where it cannot cover a game button. Only at desktop
   widths does it revert to the visually-hidden keyboard affordance. */
