/* Fallback for browsers not supporting :has or if the previous selector is too specific/tricky */
/* Simplified version that assumes .step-image has an img if we want to show the hint. 
   Actually, strict CSS :has support might be limited in some envs, but we'll assume modern. 
   If not, just .step-image:hover::after is fine, but it might show on placeholders. 
   Let's just use a JS class or rely on the fact that placeholders don't have img tags usually or we can target .step-image img directly? 
   No, the ::after needs to be on the container usually to be positioned relative to it EASILY using absolute positioning.
   
   Better approach: Only apply the hint if it contains an image.
   Since I cannot assume :has, I will just apply it to .step-image and maybe I should add a specific class like 'zoomable' to those with images in HTML?
   Or just let it be. If a placeholder is there, "Click to zoom" might appear.
   Wait, placeholders are .placeholder-img divs. They don't have the <img> tag directly inside .step-image usually?
   Looking at HTML:
   <div class="step-image">
      <div class="placeholder-img">...</div>
   </div>
   vs
   <div class="step-image">
      <img ...>
   </div>
   
   So I can target `.step-image:has(img):hover::after`. 
   If :has is not available, I'll just accept it might show on placeholders (which is not ideal) 
   OR I'll modify the HTML to add a class `zoomable` to the parent div. 
   I'll modify HTML to add `zoomable` class to the `.step-image` divs that contain images. 
   That's safer.
