/**
 * PDFAC Dashboard Layout v1.0.0
 *
 * Mirror of acp-dashboard-layout.css from Web Checker, adapted for PDF Checker.
 *
 * This stylesheet ADDS new layout wrappers and styling. It does NOT modify
 * any existing classes or selectors. All existing functionality (PDF.js preview,
 * tabs, AI handoff, AI explain, PDF export, structure panel) continues to work.
 *
 * Structure (from outside in):
 *   .pdfac-dashboard                  — root wrapper (added to #pdfac-results)
 *   .pdfac-dashboard-sticky-header    — filename + score + compliance + actions
 *   .pdfac-dashboard-pdfua-banner     — PDF/UA Validation banner (replaces fw-banner)
 *   .pdfac-dashboard-filter-bar       — All / Critical / Warning filter buttons
 *   .pdfac-dashboard-grid             — 2-column layout (main / sidebar)
 *     .pdfac-dashboard-main           — preview + issues
 *     .pdfac-dashboard-sidebar        — Quick Nav + Page Nav + AI Handoff
 *
 * @version 1.0.0
 * @package PDFAccessibilityChecker
