/*
 * Salt City Siding: site styles. Mobile-first.
 * Breakpoints: 768px (48em), 1024px (64em), 1280px (80em).
 * Changelog:
 *   2026-10-16  Created (Little Apple Tree Service template).
 *   2026-10-18  Self-hosted fonts.
 *   2026-10-20  Salt City Siding: slate-blue and salt-white palette, wheat-gold CTA,
 *               Barlow Condensed, salt-crystal logo, lap-siding hero.
 *   2026-10-21  Adam's direction: restrained light interface so the siding photos
 *               carry the color. About 60% white, 25% navy (header, footer, closing
 *               band, headings), 10% gray, 5% orange (CTA only); sky blue only for
 *               links, the logo and small accents. Manrope headings, Inter body.
