/*
    Self-contained styling for the v4 compatibility demos.

    Deliberately NOT the site's Tailwind build: these pages exist to prove that
    unmodified v4 markup runs on v5, so they must not acquire a dependency on
    anything a customer copying the page would not have. It also keeps them out
    of the checked-in-Tailwind trap, where a class that was never compiled into
    the shipped stylesheet silently renders unstyled.
