/* QuietCheck — shared site stylesheet.
   Simple and legible on purpose — this is prepared as hosting-ready material for
   Firebase Hosting, not a real design pass. Colors match the app's actual brand gradient
   (see QuietCheck/Core/BrandGradient.swift: #4F46E5 -> #FF3D68), sourced from the same app
   icon SVG as everywhere else in this project, not picked arbitrarily for the web. */
