/* The Market Regimes chapter's shell (showcase/chapters/_regimes.html, regimes.js) on /how-it-works/
   (#regimes): the tab bar, the tabpanels and the CTAs. Each panel inside a tabpanel has its own
   stylesheet (regime-intraday.css, regime-swing.css, regime-investing.css); nothing here styles a panel.
   The tab bar matches the Theta and AiPe chapters' tool tabs. Everything is rg-* and scoped under .rg
   so it beats landing.css's element reset. Only transform and opacity animate, and nothing does under
   reduced motion. */
