/* Sample Reports — picker + Original-vs-Explained comparison.
 *
 * Two visual worlds live here:
 *   1. The page chrome (header, picker grid, segmented toggle) borrows the
 *      LANDING site's light palette so this reads as part of the marketing site.
 *   2. The "Explained" panel (.app-report) is a faithful port of the EXPO app's
 *      dark report surface — tokens mirrored from app/constants/theme.js and the
 *      render logic from app/app/(app)/documents/[id].tsx — so what a visitor
 *      sees is what the real app renders.
