/* ============================================================================
   PORTFOLIO — STYLESHEET

   Design brief (spec.md): the interface stays quiet, the artwork carries all
   the colour. Near-neutral ground, generous space, one typeface at two sizes.
   The accent is pulled from the drawings, not invented.

   Palette source: six painted portraits. Burnt orange / terracotta is the
   through-line in every one; deep midnight navy is the recurring counterpoint
   (backgrounds of "Curls", "Russian Gurl", "Sun & Moon"). The accent below is
   that terracotta, sampled from the work and used ONLY for focus rings and
   link underlines — never as fill, never as decoration.

   Typeface: Newsreader — a quiet, catalogue-weight serif. Set small on purpose.
   Its italic does the exhibition-label work (tagline, tile captions).
