/* ==========================================================================
   Skrivna Design System — The Reading Room & Writer's Archive
   A quiet, editorial design with warm paper, dark charcoal ink, Literata serif,
   and zero intrusive algorithmic distraction.

   Rules of the house:
   - Every surface color comes from a token on :root; the dark-mode block
     remaps tokens, never individual rules.
   - Outlines are never removed; keyboard focus shows :focus-visible.
   - Writer language in copy, canonical glyphs (● ◇ ✦ ◌) in ornament.
