/* ===== HEADER AND FOOTER COMPONENT STYLES ===== */

/*
HEADER AND FOOTER SYSTEM:
Provides consistent navigation and branding in header,
with multi-column link structure and copyright info in footer.

STRUCTURE:
- Header: Navigation bar with logo, links, CTA button, mobile menu
- Footer: Multi-column link sections with copyright and social links

DESIGN APPROACH:
- Header: Sticky, minimal design with clear hierarchy
- Footer: Dark background with organized link columns
- Both: Use design system colors, spacing, and typography
