/* Rich methodology-guide layer (extracted from the approved leading-tasks v3).
 * Scoped entirely under body.gd-rich; stacked over home-parity.css + guides.css
 * by guide_rich_base.html. Components: sticky/mobile outline (nav.gd-outline),
 * gd-ref citation links, gd-steps-c colored step circles, gd-kicker--1/2/3
 * colored walkthrough kickers, offset-shadow instructional frames,
 * gd-product-chapter overrides (frameless evidence), gd-cta-glow animated CTA.
 * Guides opt in per component and may re-tint via the custom properties below.
 * Drift stops = the product setup-guide palette (dendropad/setup-guide.html).
