 *
 * DEVELOPER NOTES
 * ───────────────
 * This stylesheet provides the shared visual foundation for ALL standalone
 * document pages in the Bulisolio marketing SPA (Phase A). It is the single
 * source of truth for design tokens, navigation, hero sections, table of
 * contents, content typography, search widgets, content boxes, and footer
 * styles that were previously duplicated across 7+ inline <style> blocks.
 *
 * Files that consume this stylesheet:
 *   - how-smart-contracts-work.html (18-section educational guide)
 *   - eula.html (End User License Agreement)
 *   - privacy-policy.html (Privacy Policy)
 *   - affiliate-rules.html (Affiliate Program Rules)
 *   - truth-in-lending.html (Truth in Lending Disclosure)
 *   - branding.html (Brand & Design System Reference)
 *   - affiliate-landing.html (Affiliate Marketing Landing Page)
 *   - bulisolio-glossary.html (Crypto Glossary)
 *   - feedback.html (Product Feedback & Bug Report)
 *
 * Each page retains a minimal inline <style> block for page-specific
 * components only (tables, grids, cards unique to that document).
 *
 * END-USER NOTES
 * ──────────────
 * This file controls the look and feel of all Bulisolio educational and
 * legal document pages. It ensures a consistent, premium reading experience
 * with the Bulisolio brand identity: deep forest green backgrounds, gold
 * accents, Cinzel display font for headings, and Nunito body text.
 *
 * The page layout uses a two-column design on desktop (sidebar table of
 * contents + main content), collapsing to single-column on mobile devices.
 * On mobile, the pamphlet navigation system (bulisolio-pamphlet.js) takes
 * over from the sidebar TOC.
