/* ---------- SEO content section ----------
   Substantial reader-facing content below the play surface. Primarily
   for search-engine indexing — the JS-rendered game shell above is
   too thin to rank well on its own — but designed to read like a
   genuine "About this trainer" panel for visitors who scroll down.

   Visual design rules:
     - Slightly contrast-lifted background so it's clearly its own
       section, not part of the play surface.
     - Long-form typography: wider line-height, narrower max-width
       than the game shell, larger body font for comfortable reading.
     - Plays nicely with the dark theme — reuses the existing color
       tokens.
