/* Shared navigation chrome for long pSEO pages.
 *
 * Provides three components, all opt-in via separate elements in the page:
 *   - Cross-page switcher pill bar  (#msc-pagenav-switcher, server-rendered)
 *   - Sticky right-rail TOC + mobile drawer  (built by page-nav.js)
 *   - Top-of-viewport scroll progress bar  (built by page-nav.js)
 *
 * Colour tokens reuse the per-page CSS variables already defined on the
 * zodiac forecast pages: --deep-brown, --gold, --cream-light, --warm-white.
 * Falls back to hex literals if the host page hasn't defined them.
