/**
 * Out of Class Tracker — page-specific styles (Phase 1 migration)
 *
 * outofclass.html shares a "logging page" component library with
 * infringements.html: css/unified-logging-system.css (analytics-card,
 * empty/loading states, modal header/summary-chip pieces, and the
 * --accent-color/--accent-gradient vars set per-page via
 * body[data-page="outofclass"] — info/navy for this page), css/
 * unified-form-layout.css (.unified-form-section base card),
 * css/unified-student-search.css and css/form-workflow-polish.css (modal
 * overlay/container/body/footer structure + animation). All of that is
 * left untouched — this file only supplies what's genuinely page-specific
 * and was previously buried in a ~2200-line inline <style> block
 * (glassmorphism cards, hover shimmer sweeps, animated gradient borders,
 * a dead .dark-mode.* block — body.dark-mode is never set anywhere,
 * theming is data-theme driven — and a submit button/step header
 * hardcoded to purple, inconsistent with the page's actual info/navy
 * --accent-color; both now use --accent-color/--accent-gradient instead).
 *
 * Loaded LAST (after the shared files above) so these page-specific
 * rules win ties without needing !important.
