/**
 * ==============================================================================
 * Curious Rabit Design System — Unified High-Contrast sRGB Specification
 * ==============================================================================
 * Colors:
 *   - Header Background:            #0A161A (Ultra Dark Charcoal-Green)
 *   - Primary Page Background:      #F0F0E0 (Clean Off-White)
 *   - Primary Text & Headings:      #0D1C22 (Deep Charcoal-Green)
 *   - Secondary / Paragraph Text:   #3B4E49 (Dark Muted Green)
 *   - Accent / Primary CTA:         #B8E82B (Vibrant Lime Green)
 *   - Secondary Buttons / Badges:   #FFFFFF (Solid White with #0D1C22 text)
 *
 * Cross-Browser Verification (Chrome, Safari, Firefox):
 *   - Explicit sRGB color definitions
 *   - -webkit-font-smoothing: antialiased
 *   - -moz-osx-font-smoothing: grayscale
 *   - color-scheme: light only (prevents unwanted Safari dark mode overrides)
 *   - Contrast Ratios:
 *       #0D1C22 on #F0F0E0 = 13.62:1 (WCAG AAA)
 *       #3B4E49 on #F0F0E0 =  7.31:1 (WCAG AAA)
 *       #0D1C22 on #B8E82B = 10.68:1 (WCAG AAA)
 *       #FFFFFF on #0A161A = 17.50:1 (WCAG AAA)
