/*
 * DSP Chat v2 — Admin Panel
 * Slack-style light admin overlay.
 *
 * Loads AFTER admin.html's inline <style> block (which is dark by default).
 * Strategy:
 *   - Scope under .admin-panel / .login-container for natural specificity wins.
 *   - !important is reserved for fighting inline style="..." attributes.
 *   - Tenant accent (--accent-color) drives primary buttons, active-nav indicator,
 *     and stat numbers. Sidebar bg is fixed neutral dark, independent of tenant.
