/* ==========================================================================
   Header Styles — Best Plumber (Variation B: Transparent Overlay)
   ==========================================================================
   NO utility bar. Header floats over the hero with a transparent background,
   white text, and ghost-style CTA. On scroll past 80px, JS adds
   .site-header--scrolled which transitions to solid white with dark text,
   solid CTA, and a subtle shadow.

   Key design choices:
   - Absolutely positioned over hero (not in document flow)
   - Subtle bottom border (white 10% opacity) in transparent state
   - Nav links use a sliding underline from left (not center-out like VA)
   - Ghost CTA with 1px border in transparent mode, solid red when scrolled
   - Phone number uses accent (gold) icon for warmth against dark hero
   - Logo gets a subtle drop-shadow for legibility on busy hero images
   - Smooth 400ms transition between states (slower than VA for elegance)
