 * ============================================================
 * PURPOSE:
 *   The shared design system for the entire public website.
 *   Contains all colors, fonts, spacing, and reusable styles.
 *   Changing something here affects all public pages at once.
 *
 * WHAT IS DEFINED HERE:
 *   - Color palette (navy, sky blue, cream, gold)
 *   - Typography: Cormorant Garamond (headings) + Montserrat (body)
 *   - Navigation bar styles (logo, links, mobile hamburger)
 *   - Button styles (primary, outline, ghost)
 *   - Form input styles
 *   - Alert boxes (success / error)
 *   - Footer layout
 *   - Utility classes used across pages
 *
 * COLOR SCHEME:
 *   --navy-deep:  #0D1B2E  Darkest background
 *   --navy:       #1B2A4A  Mid background
 *   --blue-light: #5B8DD9  Accent blue
 *   --sky:        #A8C4E0  Light blue text
 *   --cream:      #F4F7FB  Near-white text
 *   --gold:       #C9A84C  Gold accent
 *
 * NOTE: The Admin Dashboard (admin/dashboard.html) does NOT
 * load this file. It has all styles built in to avoid conflicts.
