/* public/assets/styles/integrio-splash.css
   Shared by public/index.html boot splash and FuseSplashScreen.
   Spec: docs/superpowers/specs/2026-07-24-web-loading-splash-design.md

   Palette is Integrio's: #1C2450 primary / #283264 secondary, the same values
   themeColorHandler applies to the INTEGRIO theme. Layout, timings and the
   reveal animation are SiteSurvey's originals and are unchanged — only the
   colours and the wordmark differ. The filename is left as-is because it is an
   internal reference used by index.html, not user-visible branding.
