/* ============================================================
 * BIOTA · SECTION · Header  (part: header.html)
 * Ported from the "Biota Navbar 1a" reference.
 * Tokens: #102C57 navy · #2563EB action · #25D366 WhatsApp · #128C4B chat-green
 * Type:   Poppins (wordmark/buttons) · DM Sans (links)
 *
 * Bar state is driven by a .solid class on #sitenav (added by header.js on the
 * home hero at scrollY > 80). Non-home pages are solid from the start via CSS,
 * so there is no first-paint flash and no JS dependency there.
