/* Ensure logos look okay on dark mode if they are transparent pngs. 
   If they have white backgrounds, we might need a white container. 
   The original CSS had background: #fff; for .carousel-container.
   Let's keep it #fff for logos if they rely on it, but use variables if we can. 
   Most logos seem to be PNG/SVG. If they are dark text, they need light BG.
   If they are white text, they need dark BG.
   Looking at images: 'schwab.png', 'Broadridge...svg'.
   Usually company logos are colored/dark.
   Let's force a lightish background for the carousel track AREA even in dark mode?
   Or better: keep the original #fff background for the carousel container to ensure logo visibility,
   or enable a "dark mode compatible" logo set.
   Given the file list, we don't have separate dark logos.
   So let's keep the carousel container white-ish or adapt carefully.
   Original was `background: #fff`.
   Let's try `background: rgba(255,255,255, 0.9)` in dark mode to ensure logos show up?
   Or if logos are white text...
   Let's check the logos. Schwab is blue/black. Randstad is blue.
   They need a light background.
