    be active, matching the marketing homepage

    Odoo ships two demo website records out of the box
    (website.default_website, website.website2), both created with
    noupdate=True. A plain <record> write targeting either from this
    module's own data files is silently skipped - no error, nothing in
    the log - exactly the same trap demo/mc_cast_users_demo.xml already
    documented for an unrelated field. Running this as real Python
    instead isn't subject to that guard.

    Only runs on a fresh install of this module, per Odoo's own
    post_init_hook contract - it will not re-fire on `-u` of a database
    that already had this module installed before this hook existed.
