/* Universal reset for the legacy public lookup SPA. Margin +

           it beats Tailwind v4 utilities (which live in @layer utilities
           and can't override unlayered rules). Earlier attempt used
           `*:not(.portal-root, .portal-root *)` but Chrome's CSS parser
           dropped the compound :not() and reverted to bare `*`. Now we
           ONLY zero padding via a class-targeted rule on the legacy app
           wrapper, leaving portal subtree intact. */
