/* =============================================================================
   derek.css — 04.64f
   The public Derek FASCIA stream at /derek/.

   Time-shaped, not portfolio-shaped. The page is a column of dated entries with
   a masthead above and a shelf below; there is no grid of cards, no tile wall
   and no "featured work" hierarchy, because the point is that this accumulates
   rather than presents. Entries are separated by a rule and a date, which is
   all a stream needs.

   Typography is the existing AMSP set: Libre Baskerville (--display),
   Montserrat (--body), IBM Plex Mono (--mono). No new families are loaded.
