   NOTES PAGE CUSTOM STYLES
   Extends turbolearn-darkmode.css base theme
   ============================================ */

/* ===== MAJOR CHANGE #3: CSS Custom Properties (Variables) ===== */
/* BEFORE: Colors were hardcoded like #1a1f2e, #667eea, rgba(26, 31, 51, 0.6) */
/* NOW: Uses CSS variables that automatically change with light/dark mode:
   - var(--bg-paper): Main background
   - var(--bg-card): Card backgrounds
   - var(--text-primary): Main text color
   - var(--accent-terracotta): Primary accent color
   - var(--border-light): Subtle borders
   - var(--shadow-md): Consistent shadows
   These variables are defined in turbolearn-darkmode.css and change values
   when data-theme attribute switches between "light" and "dark"
