/* ==================================================================
   Vaseline Cloud Soft × Jetour — campaign page

   Built to the supplied artwork. Every number below is measured from
   "Vaseline Cloud Screens AW.psd" on its native 1080 × 1920 canvas.
   --u is one design pixel, so `calc(50 * var(--u))` is literally the
   50px the designer drew. Nothing is floored: the page is a 1:1 render
   of the artwork at EVERY width. On a 375px phone that means ~5.4px
   labels, so pinch-zoom is deliberately left enabled.

     logo      75,181   533 x 195      card      42,530   996 x 677
     tub      621,101   432 x 401      headline 195,1234  690 x 105
     car       33,1444  967 x 476      jetour   254,1356  572 x  56
