 * CMS HTML articles — SHARED stylesheet (one file for all uploaded HTML articles)

 * Loaded in the HTML-article iframe after css/article-guide.css (see js/main.js buildCmsHtmlSrcdoc).
 * Deploy: commit + push; Vercel serves /css/cms-html-shared.css for every CMS page.
 *
 * Workflow: paste new article HTML in chat; assistant extends this file if needed; you paste body HTML only in admin.
 *
 * Hub-and-spoke diagrams:
 * - .hub-container + .spoke-node (fixed positions) + optional SVG .hub-spokes-svg (dashed lines)
 * - or .hub-wheel with .hub-spokes > .hub-spoke.hl-* and .hub-node-slot.hns-0…5
 * - .type-cards + .tcard.tc-blue|tc-green|tc-purple (integration type summaries)
 * - .dir-grid / .dir-card-* (inbound vs outbound) or .dir-card.dc-* (sync vs async lists)
 * - .timeline / .tl-* / .tb-* (integration timing visuals), .code-block + .ck/.cs/… (manual Apex)
 * Inline <svg><line> spokes are allowed by the backend sanitizer; use viewBox on <svg>.
