/* =============================================================================
   ledgenter.css — the "midnight office" design system.

   Concept: Ledgenter's own mental model is an OFFICE — projects are initiatives,
   tasks are the work, decisions are meeting minutes, the activity feed is the
   building logbook. The site renders that office after hours: warm espresso
   ink, paper-cream type, one desk-lamp amber, blueprint hairlines, and the
   quiet hum of agents still working. Fraunces (editorial display) ×
   Instrument Sans (body) × IBM Plex Mono (the agents' voice).
