/**
 * Aitrixa FAQ — page-specific styles.
 *
 * Loaded only on pages using the FAQ template (page-faq.php). Depends on
 * assets/css/aitrixa.css being enqueued first for the design tokens
 * (--ink, --page, --line, --font-serif, --font-sans, --font-mono, etc).
 *
 * Source of truth for the visual: pages/Aitrixa FAQ.html (the inline <style>
 * block in that file). The unused .faq-nav rules from that file (it was a
 * deprecated category nav, display:none in the mock) are intentionally
 * omitted here.
