/*
 * 現場レポートPDF — public site shared styles.
 *
 * Design intent:
 *   - White base with a navy (#0F2D5C) primary and softer accent blue.
 *   - Card-based composition; rounded corners; generous breathing room.
 *   - System fonts only. No web fonts, no CDN, no JS, no analytics.
 *   - Mobile-first. Layouts collapse to a single column under ~600px.
