/* ============================================================
 * Trueleveler — Blog post layer
 *
 * Re-skins the legacy blog post markup (article-header / article-body /
 * callout / contract-quote / inline-cta / related-section) using
 * Blueprint Amber tokens. Pair with blueprint-amber.css.
 *
 * Markup conventions kept from the v1 blog template so 177 posts can
 * be migrated by chrome-only swap (style + nav + footer) without
 * touching per-post body markup.
 *
 * SOURCE OF TRUTH: this file. blueprint-amber.css owns nav/footer/btns.
