/**
 * Phone-width screenshots of the Phase 5 dashboard.
 *
 * Evidence for AUD-109: the per-child dashboard (overdue first) and the item
 * detail screen at a phone width (390 x 844). It logs into the live service with
 * the dashboard session login, then follows the child tabs and the first overdue
 * item.
 *
 * Usage (secrets from the environment, never committed):
 *   SCHOOL_USER=sam SCHOOL_PASS=... node scripts/screenshot-phase5.mjs
 *
 * Environment:
 *   SCHOOL_BASE       default https://school.lab.audasmedia.com.au
 *   SCHOOL_SHOT_DIR   default var/screenshots (git-ignored)
 *   COMPASS_CHROME    default /etc/profiles/per-user/sam/bin/google-chrome
 *
 * The output is personal data (children's homework). It stays under var/
 * (git-ignored) and is only uploaded as issue evidence.
