Notes

A cinematic hero for a laundry collection service: the brand colour becomes a lit mesh built from five stacked radial and linear gradients on the band Div, with three app cards floating over it at different depths. The mesh uses relative oklch colours of the brand, so it follows the site colour, and the band keeps a plain brand background underneath for browsers without relative colour support. The cards are plain Divs: each sits in its own full-width wrapper with a negative top margin, so later cards paint over earlier ones, and the translucent back card and deeper shadows sell the depth. From phone landscape down the three cards stack as a staggered deck with a 10px tuck, so keep the bottom padding on the upper two cards if you change the overlap.
