   All imagery is generated by _src/make_images.py - original work, no stock,
   no licence obligations. Heroes carry the image as a background layer under
   the existing gradient so text contrast is preserved regardless of the
   image behind it. Every slot degrades gracefully if the file is missing:
   the gradient alone was the previous design and still stands on its own.
