/* assets/search.css
   ---------------------------------------------------------------------------
   Palette and type borrowed from ~/code/Portfolio: zinc ground, hairline
   borders, Cal Sans for display type, a sky focus ring.

   Hand-written rather than Tailwind: this is one stylesheet and the project
   has no node toolchain.

   Breakpoints (min-width, mobile first):
     -        0     single column, rail collapsed into a disclosure
     --bp-sm  30rem / 480px   two-up result metadata, roomier spacing
     --bp-md  48rem / 768px   inline search button, wider gutters
     --bp-lg  64rem / 1024px  rail becomes a permanent sidebar
     --bp-xl  90rem / 1440px  wider shell, larger measure

   Media queries cannot read custom properties, so the rem values above are
   repeated literally at each @media. Change both.
