    to the active team (a hidden field, not a picker -- there's no "which
    team" question on a screen that's already scoped to one), and ``groups``/
    ``club_wide`` are dropped entirely, since both widen the audience past a
    single team the same way multi-team selection would. ``invited_members``/
    ``excluded_members`` stay, re-scoped to sensible pools (add someone not on
    the roster; exclude someone who is) rather than "every club member" --
    the template spells out that a genuinely multi-team event still needs the
    desktop. Location/opponent are rendered via the standalone
    _location_picker/_opponent_picker (see their own docstrings), each with a
    "+ New" popup (CoachLocationCreateView/CoachOpponentCreateView) for when
    the one needed doesn't exist yet.

    One screen creates either a single Event or a recurring EventSeries --
    ``is_recurring`` (a plain checkbox) picks which of the two forms below
    actually validates the request; the two share every audience/location/
    opponent field (identical names), so nothing needs duplicating in the
    template, just shown/hidden. Competition has no EventSeries equivalent
    (EventSeriesForm carries no such field), so it's one-off-only.

    After a successful single-event save: the same notify_new_event.delay(...)
    call management.views.EventCreateView.form_valid makes -- attendance sync
    is automatic via events/signals.py, only the notification dispatch needs
    replicating by hand for a view that isn't a CreateView. A new series
    mirrors management.views.EventSeriesCreateView instead: generate_occurrences
    materialises its occurrences immediately (each one syncing its own
    attendance the same way), but -- matching that same desktop behaviour,
    not a mobile-specific gap -- nothing pushes a "new event" notification per
    occurrence; a bulk-created series relies on send_deadline_reminders' own
