/*
 * RentaNet CSS - Refactored
 * 
 * COLOR SYSTEM:
 * - accent: Brand red, for buttons, highlights, links on hover
 * - text-primary: Main readable text
 * - text-secondary: Softer readable text (NOT accent colored)
 * - text-muted: Least prominent text
 * 
 * KEY PRINCIPLE: Never use accent red for body text that needs to be read.
 * Red on dark = poor contrast. Use white/light gray for readable text.

 * LIGHT MODE NAV OVER DARK HERO

 * Fix: Force white nav elements in light mode when NOT scrolled.
