/* Zero custom classes anywhere -- every rule targets a native HTML element,
   an id (one page section/widget each), or an attribute.

   Colors are base16 (https://github.com/chriskempson/base16): swap the
   --base0X values for any published base16 scheme's hex codes to reskin
   this completely, in either light or dark, no other edits needed. Default
   below is base16-default (chriskempson), light and dark variants picked
   automatically via light-dark().

   Layout is deliberately dense and undecorated -- inspired by Hacker News,
   lobste.rs, and Miniflux: minimal chrome, small type, no cards/shadows/
   rounded corners, content over decoration. See Miniflux's own case for
   this (https://miniflux.app/opinionated.html) if you want the reasoning.
