  Production UI layer, safe version.
  This file is intentionally scoped to .ui-* and data-ui-* classes so it does
  not override Tailwind utility classes such as .hidden, .flex, .grid, md:flex,
  lg:flex, etc. The previous package used a global .hidden rule and shell-level
  selectors; this version removes those overrides to restore the public pages,
  login access and authenticated sidebar behavior.
