/*
 * ============================================================
 * authenticated-shell.css
 * Shared visual foundation for all authenticated app pages.
 *
 * Defines:
 *   1. Design tokens (surface, border, shadow, radius, typography, accent)
 *   2. Page container / header / spacing
 *   3. Surface classes (card, panel, muted, widget)
 *   4. Stat tiles
 *   5. Widget layout (title, link, list, item)
 *   6. Side-panel stack
 *   7. Interaction polish (hover elevation, focus, link treatment)
 *
 * Usage:
 *   Every authenticated page should wrap its content in .app-page.
 *   Page headers should use .app-page-header / .app-page-title / .app-page-subtitle.
 *   Cards use .surface-card, panels use .surface-panel,
 *   nested metadata blocks use .surface-muted.
 *   Widget panels use .surface-panel + .widget-title / .widget-list etc.
 *   Stats use .stat-grid / .stat-tile / .stat-label / .stat-value.
 *   Right-column widget stacks use .app-panel-stack.
