/* ============================================================================
 * sf-admin.css — Skillfull design system
 *
 * The single source of truth for the look of every admin-grade page in the
 * app: /admin/* (Tenant area), /profile/* (learner area), Operations, and
 * the public profile page. Loaded from each area's _layout.cshtml.
 *
 * The project was scaffolded on the Phoenix Bootstrap theme and is slowly
 * replacing Phoenix classes with sf-* primitives. Bootstrap utilities are
 * still in play (text-truncate, table-responsive, grid columns, badges);
 * Phoenix-specific things (.btn-phoenix-secondary, .text-body-tertiary)
 * are honoured but we don't add new dependencies on them.
 *
 * Section index:
 *   1. Containers          — page-level max-widths
 *   2. Hero bands          — top of every admin page
 *   3. Cards               — sf-card, sf-stat, sf-kpi, sf-integration
 *   4. Tiles               — sf-shortcut, sf-action (clickable cards)
 *   5. Components          — avatars, icon circles, line-clamp, etc.
 *   6. Calendar            — sf-cal-* monthly grid
 *   7. Upload drop zone    — branding image picker
 *   8. Reports event rows  — sf-ev-*
 *   9. Status rings        — ring-warning / ring-danger
 *  10. Gradient palette    — sf-grad-* (used on icon circles)
 *  11. Design tokens       — :root --sf-* shared design tokens
 *  12. Pills + status      — sf-pill, sf-status-pill
 *  13. Admin tables        — sf-table list table
 *  14. List page toolbar   — sf-list-toolbar
 *  15. Square avatar       — sf-avatar-square (non-circular variant)
 *  16. System dashboard    — sf-pulse-hero, sf-mini-card, sf-activity-row, sf-nav-strip
 *  17. Quick search        — sf-qsearch-* (Ctrl/Cmd+K overlay across Operations)
 * ========================================================================= */
