/* ==========================================================================
   Vectra AI blog index redesign mock, combined edition (2026-11-06)
   Built on the homepage and platform combined mocks (redesigns/home-combined,
   redesigns/platform-combined): the same tokens, type, CTAs, sheets and motion
   states, so the three 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).
