   Cat — "Built for it" landing
   Desktop (>= 900px): the 1200px mockup is reproduced on a fluid canvas.
   Every size is written in mockup pixels and multiplied by --u (= viewport / 1200),
   so the page keeps the proportions of the design at any desktop width.
   Below 900px the page switches to a regular responsive layout.
