/* Because there is no overlay, we must ensure text has a solid or semi-solid background box if needed,

   It says "No color overlays". Wait, the PRD says: "Dark overlay for text readability." BUT the system prompt explicitly says: "HERO IMAGE RULE — NO COLOR OVERLAYS (APPLIES TO ALL PAGES): Display hero section images exactly as they are — no exceptions... This rule overrides any color instructions in the PRD — even if the PRD specifies an overlay color, skip it for hero sections".
   So I will NOT use any overlay.
   I will add a text-shadow or a solid background box directly behind the text ONLY to ensure readability, or just rely on the image. Actually, I can put the text in a card-like container with a solid background if needed, but text-shadow is safer to keep the image visible.
