/* Hero skyline.
   A black-and-white cut-out of the City of London (assets/img/city.webp) sits in front of a sky built in CSS.
   All movement is CSS keyframes, no script and no video:
     - two cloud layers drift behind the towers at different speeds
     - soft cloud shadows and a band of light pass over the buildings (masked to the buildings only)
     - the city very slowly pushes in and out, like a locked-off camera breathing                              */
