/* Small Swope — the whole design. Hand-written CSS on Propshaft: no Tailwind,
   no build step, no watcher. Dark mode follows the reader's system setting.
   Syntax-highlighting colours live in syntax.css (generated — see lib/tasks).

   THE IDEA — two voices.

   This site is a notebook of detours, so the design gives the page two
   typographic voices and lets the contrast between them do the work:

     serif (Literata)   what a person wrote — titles, prose
     mono  (Plex Mono)  what the machine knows — dates, durations, tags, code
     sans  (system)     interface chrome — the admin's forms and buttons

   Every "nice" detail below is one of those three voices used consistently.
   Adding a fourth is how this starts looking like everything else. */
