/*
  Screen 03 — Company Intelligence Workspace.
  Layout traces to SCREEN_03_COMPANY_INTELLIGENCE_WORKSPACE.md (the
  Design-Review-refined version: Monitoring Status restored, distinct
  section jobs for Readiness/Narrative/Evidence/Explainability, a
  persistent Timeline "Today" marker) and its Visual Concept. Denser than
  Screens 01/02/05 by design — this is a daily-use investigative
  workspace, not a first impression or an interruption — but still no
  cards anywhere: hairline rules and whitespace only.
