   Plain CSS, mobile first: base rules target phones, and each component adds
   its own min-width media queries right below it.
   --------------------------------------------------------------------------
   Breakpoints (CSS variables can't be used in @media, so they are listed here):
     xs  ≥ 480px   wide phones (tiles go 2-up)
     sm  ≥ 600px   large phones / small tablets
     md  ≥ 900px   tablets / laptops (desktop nav appears)
