Major theme extension adding full-featured navigation with dropdown submenus (Tools, My Data, Resources), 9 new page templates (Calculator, Protocol Builder, Tracker, Subject Log, Documentation, Directory, Science Feed, Profile, Sign In/Register), documentation page with sidebar ToC and scroll spy, branded AJAX authentication forms, newsletter signup with admin export, slide-out contact/support panel, Research Modules 6-card grid on front page, and comprehensive footer update. Split functions.php (554→206 lines) into 6 focused inc/ modules: helpers, customizer, auth-handlers, contact-handler, page-setup, newsletter-admin. All new components include dark mode support, CSRF protection, input sanitization, output escaping, and graceful plugin degradation via shortcode_exists().
