   Lumen — shared design system
   Medical-grade, high-contrast, WCAG 2.1 AA. Deep-indigo / teal accent.
   This file is the canonical theme; it is copied verbatim into each app folder
   (reader/, portal/, review/) so every app deploys as a self-contained Pages
   project. Edit shared/lumen.css and re-run scripts/sync-theme.sh to propagate.
