ExportBridge is a custom-built WordPress theme following WordPress Coding
Standards, designed for a B2B export consulting and trading business.
It is RTL-first (Persian), structurally ready for Arabic via
Polylang/WPML, and built around Semantic HTML + JSON-LD Structured Data
for both traditional SEO and AI answer-engine discoverability (GEO).

/* This stylesheet intentionally holds only the WordPress-required header +
   design tokens + minimal base/reset layer. Component-level styles for
   header, footer, hero, services, FAQ, cta, and contact are organized in
   separate files under assets/css/ and enqueued via inc/enqueue.php, so the
   theme stays maintainable as it grows (see inc/enqueue.php in an upcoming step). */
