   - AI button: better dark mode (auto + manual + force)
   - AI button: z-index 2147483000 (max, above everything)

 * v25.1 FIX-EEAT-BOX: "About the Author" card
 *
 * - Class-based (no inline styles) so dark-mode rules can override cleanly.
 * - Light theme: gradient #f8fafc → #f1f5f9, text #1e293b.
 * - Dark theme: solid #1e293b, text #e2e8f0. Triggered by either:
 *     1. Browser/OS dark mode  → @media (prefers-color-scheme: dark)
 *     2. Hostim theme toggle  → [data-bs-theme="dark"] on <html> or <body>
 *
 * NOTE: We deliberately use !important on the dark-mode colors because the
 * Hostim theme loads its CSS AFTER the plugin's frontend.css (themes
 * typically register at priority 10, plugins at default 10 — order varies).
 * !important guarantees the dark palette wins regardless of load order.
