       a multiple of --u ("one HUD pixel"), so the whole interface
       grows and shrinks together, keeping its proportions:
         - phones (up to 600 px wide): about 1.4-1.5x the original
         - laptops and 1080p screens: about 1.35-1.45x
         - 1440p: about 1.8x;  4K: about 2.5x (the most)
       It follows the screen's shorter side, so a big monitor gets
       big text and a phone held sideways stays compact. (Media
       queries further down set it for phones and short screens.)
