  Each .bg-layer holds one photo as a background-image.

  Color treatment:
    saturate(2.1)   → punches up the color vibrancy (feria poster feel)
    contrast(1.45)  → crunches the tones, makes darks darker / brights brighter
    brightness(0.75) → pull overall exposure down slightly so the overlay reads

  image-rendering: pixelate + scale(1.04):
    The slight upscale forces the browser to use the pixelate algorithm
    on sub-pixel boundaries, adding a barely-there blocky texture without
    looking like generic pixel art. (Subtle — exactly as requested.)

  Opacity transition creates the crossfade when JS toggles .active.
