/* Everything is sized from one unit, --u (the body text size, = 1rem), so the whole
   page scales as one piece and fits the screen without scrolling.
   - Wide screens, where the text column hits its max width: the page height grows
     with --u, so --u follows the screen height (--k-tall × svh).
   - Narrower screens, where the text fills the width: the largest --u that fits
     was measured over a grid of window sizes and is close to a straight line in
     height and width; --k-h × svh + --k-w × vw sits about 6% under it.
   Measured across phones, tablets and desktops in portrait and landscape. */
