/*
 * docs.css
 * Shared stylesheet for the four "document" marketing pages:
 *   /accessibility · /faq · /shipping · /terms (and /terms/accept typography)
 * Replaces accessibility.css, faq.css, shipping.css and terms.css.
 *
 * Structure:
 *   1. Shared .doc-* primitives — sticky TOC sidebar (+ .is-active state),
 *      the TOC/doc two-column layout grid, doc-column typography, and the
 *      shared responsive collapse.
 *   2. Page deltas — small overrides scoped by a page class on <main>
 *      (.ac-main / .faq-main / .sp-main / .tp-main). The body class is
 *      ft-page for all four pages, so page scoping lives on the main element.
 *   3. Page-unique blocks kept under their old prefixes:
 *      .ac-*  accessibility contact/feedback blocks + dot lists
 *      .faq-* accordion (+ eyebrow, category groups)
 *      .sp-*  shipping-methods table (+ disc lists, doc grid rhythm)
 *      .tp-*  terms legal typography (blocks/lists also used by /terms/accept)
 *
 * Reuses the global .ft-* foundation (foundation.css, linked before this file)
 * for tokens: --ft-blue #2da7fa · --ft-text #333536 · --ft-muted #737a82 ·
 * --ft-border #e4e4e4.
