   wwa-chrome.css  —  Wild Wild Agents shared chrome (head-nav + footer)
   BBE-STD-WWA-CHROME-001 · v20260701
   Hosted: https://hub.wildwildagents.com/chrome/wwa-chrome.css
   Pairs with wwa-tokens.css + wwa-chrome.js. Emoji-free, SVG icons only,
   CI toggles (no native select/checkbox), WCAG 2.1 AA in light + dark.
   Namespaced .wwa-* so it never collides with a host page's own CSS.
