    "Limit this offer to" — the plans an offer may be used on.

    Nothing ticked means every plan, which is how every offer behaved when there
    was only one. That default matters: an offer saved with nothing selected must
    keep working everywhere rather than working nowhere.

    Checkboxes rather than a multi-select, because a multi-select gives no hint
    that more than one can be chosen and quietly loses the others when someone
    clicks a second.

    $prefix    unique id prefix, so Add and Edit can both exist on the page
    $plans     the plans on sale
    $selected  ids already chosen; empty when adding
--}}
@php $selected = collect($selected ?? [])->map(fn ($id) => (int) $id)->all(); @endphp

             Worth setting for a fixed amount off: $20 is a quarter off the cheapest
             plan and a fraction of the dearest, so the same code is a different deal
             depending on what the customer picks.'])
