/* AI Accuracy Lab · "Send feedback" panel
   Load on every page (public and signed-in), AFTER site.css and hball.css.
   Every class here is new and prefixed fb-, except .ftr-fb (the footer trigger, which sits beside .ftr-links a).
   Uses the site's own tokens (--ink, --muted, --hairline, --ground, --surface, --link, --cta) and classes
   (.btn, .btn-primary, .btn-secondary, .hdot, .sr-only). Nothing in site.css is overridden. */
