/* ==========================================================================
   Components — Editorial Luxury
   
   Design language:
   - Nav is minimal, almost invisible — just text
   - Cards have no borders, just subtle background shifts
   - Buttons are thin-bordered, uppercase, lots of letter-spacing
   - Color is used sparingly — mostly through typography
   - Whitespace does the heavy lifting
