   7. TOUCH-DEVICE OVERLAY PARITY
   Desktop reveals the category label + "View full size" cue on :hover.
   Touch devices have no hover, so without this, that entire piece of the
   desktop design is invisible on phones — tapping a thumbnail jumps
   straight to the lightbox and the overlay is never seen. This shows the
   same overlay by default, but ONLY on devices that report no real
   hover/pointer (phones, most tablets). Anything with a mouse or
   trackpad — i.e. the desktop experience — is untouched, since it still
   matches `hover: hover` and keeps the original hover-to-reveal behavior.
