/*
 * Enosis Modern — Main Stylesheet
 *
 * Design philosophy:
 * - Confident, restrained, modern (think Stripe, Linear, Vercel — for B2B services).
 * - Generous whitespace, strong typography, tight grids.
 * - Performance-first: no shadows, gradients, or animations that block paint.
 * - Accessibility: WCAG 2.1 AA contrast on every text/background pair.
 * - Dark-mode aware via prefers-color-scheme (optional opt-in).
 *
 * Structure:
 *   01. Design tokens (CSS custom properties)
 *   02. Reset + base typography
 *   03. Layout primitives (container, grid, stack)
 *   04. Header & navigation
 *   05. Hero section
 *   06. Service cards
 *   07. Stats strip
 *   08. Approach / process steps
 *   09. Client wall
 *   10. Case study cards
 *   11. Testimonials
 *   12. CTA banner
 *   13. Contact form
 *   14. Footer
 *   15. Utility classes
 *   16. Responsive breakpoints
