   Convene landing page — /convene/ (VIV-6667)

   Loaded after /styles.css, which owns the tokens, .wrap, .section,
   .section-head, .eyebrow, .btn* and .sbx-input/.sbx-err primitives this file
   builds on. Everything here is `cv-`-prefixed and page-scoped.

   No product screenshots exist for Convene yet, so every "visual" in the spec
   is a CSS abstraction (bars, rows, chips) — no <img>, no invented asset, and
   all of it aria-hidden so the a11y tree only sees the real copy.
