Reported: clicking Back to Home in the sticky footer surfaced
Streamlit's "Page not found — Running the app's main page" message
in the user's build.
Root cause: ``url_path="home"`` on the home page's ``st.Page``
registration is treated as an alias for the default page in some
Streamlit minor versions, but the user's build doesn't honour the
alias for the page that ALSO has ``default=True``. The default page
is served at the root URL ``/``; ``/home`` is treated as a missing
page on that build.
Switch the footer anchor's href from ``"home"`` (which resolved to
``/home`` from any tool-page URL) to ``"./"`` (resolves to the
current document's directory, which on a single-segment URL is the
server root → default page → Home). Robust across Streamlit minor
versions regardless of how the url_path alias is interpreted.
