/**
 * ==========================================================================
 * iKnowMe Sovereign Engine – Main Stylesheet (v1.1.0)
 * ==========================================================================
 *
 * DOCUMENTATION:
 * This is the primary stylesheet for the iKnowMe theme. All visual styling
 * is contained here. The design uses a "Cyber-Oasis" color palette with
 * bioluminescent emerald (#00FF9D) and prism cyan (#00E5FF) accents on a
 * deep abyss background (#030708).
 *
 * Key design principles:
 * - Glassmorphism cards with subtle borders and backdrop blur
 * - Soft radial gradients for ambient lighting
 * - Smooth hover transitions and elevation effects
 * - Fully responsive breakpoints at 992px and 768px
 * - CSS custom properties (variables) for easy theming
 *
 * File Structure:
 * 1. CSS Custom Properties (Root Variables)
 * 2. Reset & Base Styles
 * 3. Navigation (incl. logo SVG)
 * 4. Buttons
 * 5. Hero Section
 * 6. Manifesto Section (NEW in v1.1)
 * 7. Governance Section
 * 8. Brands / Product Portfolio Section
 * 9. Modal (Investor Portal)
 * 10. Footer
 * 11. Media Queries
 *
 * How to customize:
 * - Change colors via the :root variables at the top.
 * - All spacing uses rem units for scalability.
 * - Font stack is system-native for performance.

 * END OF STYLESHEET
 * ==========================================================================
 * Additional notes for developers:
 * - To add a mobile hamburger menu, extend the nav with a button and JS toggle.
 * - All colors are CSS variables – change them once and the whole theme updates.
 * - The modal uses a class .is-open for accessibility and easier JS control.
 * - WordPress will automatically load this file via wp_enqueue_style in functions.php.
 * - Manifesto section added in v1.1.0 to match updated brand narrative.
