 * NTA Landing Page — Stylesheet
 * ------------------------------------------------------------------
 * Structure
 *   1. Design tokens (light = default, dark via [data-theme="dark"])
 *   2. Base / reset / typography
 *   3. Utilities & shared components (buttons, eyebrow, section heads)
 *   4. Header & navigation
 *   5. Hero
 *   6. About
 *   7. Services
 *   8. News
 *   9. Partners
 *  10. CTA
 *  11. Footer, back-to-top, toast
 *  12. Motion (reveal, float) + reduced-motion
 *  13. Responsive
 *
 * Brand colors are taken from the NTA platform (common/css/theme.css):
 *   --brand-primary #e63946 · --brand-primary-dark #c1121f
 * Layout uses CSS logical properties so RTL (ar) and LTR (en) both work.
 * Fonts: system font stacks only (no external requests, CSP-friendly).
