/* ==========================================================================
   Vectra AI blog post template redesign mock, combined edition (2026-11-06)
   Built on the homepage, platform and blog index combined mocks
   (redesigns/home-combined, platform-combined, blog-combined): the same
   tokens, type, CTAs, sheets, cards and motion states, so the pages read as
   one system. Scope: everything lives under main.rd; every class is
   prefixed rd-. Loaded after the Webflow CSS so the scoped reset wins over
   the site's global tag rules (white p/h1/h2, flex ul, 20px lh).
   Post bodies keep their custom embeds (.rd-custom: infographics, tables)
   with their own styles: the article's rules reach only the post's own
   paragraphs, headings, lists, quotes and figures.
