/* Dark theme overrides for cards if parent is dark, but design shows white cards on light grey bg.
   Assuming the theme is generally dark based on previous file viewing (dark bg colors).
   Let's check style.css again... yes, body is dark (#121212 usually or similar).
   Wait, the design image shows WHITE cards on a light background?
   Actually the user provided image has a light background mostly.
   BUT the user's current 'style.css' has background-color: #121212 (Dark Theme) in the previous context/files I saw?
   Let's re-read style.css start...
   Wait, I didn't see the body background in the view_file snippet.
   Let's assume the user wants it to look like the IMAGE provided.
   The image provided is LIGHT THEME.
   However, the user pushed for 'Dark Theme' in a previous conversation.
   I should probably stick to the theme's current aesthetic but implement the LAYOUT of the image.
   If the theme is dark, I'll make the cards dark (#1e1e1e) to match the dark theme established in previous queries.
   'style.css' snippet showed:
   .pagination a { background-color: #1e1e1e; color: #e8eaed; }
   This confirms a DARK theme is active.
   So I will make the cards DARK (#1e1e1e) with Light Text to match the existing theme, 
   adapting the 'layout' from the image but the 'colors' from the theme.
