/*
  Aquamor Website Design System — site.css
  Version: 1.0 — Phase 1 Homepage Prototype
  Author: Isla (UI/UX & Brand)

  Design principle: Precision-manufacturer web standard.
  Confident scale, generous whitespace, restrained color.
  Light theme only — single polished marketing site.
  Mobile-first. WCAG AA (≥4.5:1 contrast throughout).

  CONTRAST AUDIT (all pairs ≥4.5:1):
  - #1A1A1A on #FFFFFF = 16.0:1  ✓
  - #1A1A1A on #F5F9FC = 14.7:1  ✓
  - #1e3a5f on #FFFFFF = 10.3:1  ✓
  - #1e3a5f on #E8F4F8 = 8.4:1   ✓
  - #FFFFFF on #1e3a5f = 10.3:1  ✓  (filled buttons/badges — navy bg)
  - #FFFFFF on #1A1A1A = 16.0:1  ✓  (footer text on dark)
  - #333333 on #FFFFFF = 12.6:1  ✓  (body text)
  - #5A6B7A on #FFFFFF = 5.1:1   ✓  (header tagline — muted brand signature)
  - #4AADD4 on #FFFFFF = 2.55:1  ✗  — NEVER used for body text
  - #4AADD4 is DECORATIVE ONLY: borders, underlines, icons, wave accents
  NOTE: White text on #4AADD4 fill = 2.55:1 — NEVER used.
        All filled interactive elements use #1e3a5f (navy).
  Review Round 2 (2026-06-10): header tagline added (#5A6B7A, 5.1:1); footer
        icon logo (.site-footer__icon); header heights updated for tagline clearance.
