/*
 * ADMIN DASHBOARD STYLES
 * File: assets/css/admin.css
 *
 * WHAT THIS FILE DOES:
 *   Styles the internal admin dashboard that the AwareAI team uses to view leads,
 *   check pipeline errors, and edit the AI agents' instructions.
 *
 * USED BY:
 *   admin.html (password-protected, team use only)
 *
 * SECTIONS INSIDE:
 *   - Design tokens (colour palette — same dark navy as the rest of the app)
 *   - Microsoft lock screen overlay (shown until the user signs in)
 *   - Topbar / header
 *   - Tab navigation (Leads / Errors / Prompts tabs)
 *   - Leads table (one row per prospect session)
 *   - Error log list (failed pipeline runs)
 *   - Agent prompt editor modal (for editing AI system prompts)
 *   - Status badges (e.g. "complete", "failed", "pending")
