/* ==========================================================================
   writing.kayadshead.org — design system
   Two designed rooms: theme-light (ink on paper) and theme-dark (stage dark).
   Type: Libre Caslon Display (monument headings), Libre Caslon Text (body),
   Archivo Narrow (billing lines: dates, kinds, credits).
   Accent: curtain red. Spend boldness on the timeline spine and titles;
   keep everything else quiet.
