/* joinUs.css - the Join Us page (rebuilt 2026-09-24).
 *
 * The page answers one question - how do I join? - and it used to answer it
 * with a single centred box of bullets nested two deep, where the order of
 * the steps was implied rather than shown and the two links were small
 * unlabelled logos at the bottom. It is numbered steps now, each with the
 * one thing to click, on the shared card vocabulary the Supply Chain pages
 * set. Every link the old page had is still here: the Discord invite, the
 * RSI org page and the Officers page.
 *
 * The video and its two flanking images are unchanged.
