/*********** Updated styles.css with enhanced header, dashboard integration, and white backgrounds ***********/
/* Changes:
- Header: Added slide-in animation for nav links, teal underline hover effects, sticky header with subtle shadow.
- Dashboard: Integrated provided admin-sidebar, main-content, admin-header, and stats-card styles, adapted to teal palette.
- Backgrounds: Set all backgrounds to white (body, header, sidebar, cards, etc.) for consistency.
- Text Visibility: Used dark teal (#003d33) or black (#212529) on white, white on teal/dark backgrounds for contrast.
- Colors: Maintained calm teal palette, avoided color riot, ensured smooth blending with gradients.
- Animations: Enhanced header with nav link slide-in, preserved hero and product animations with added fade-in.
- Ensured all text is visible with sufficient contrast (WCAG-compliant).
