"""Build a QQ keyboard JSON payload from a Dify human-input form_data.
Each Dify ``action`` becomes a callback button (``action.type=1``)
whose ``data`` is set directly to the Dify ``action_id``. The
INTERACTION_CREATE event carries this back as
``data.resolved.button_data`` so the adapter can match the click to
the originating form.
Layout limits per spec: max 5 rows, max 5 buttons per row. We default
to 2 buttons per row for legibility; oversized button lists wrap
onto additional rows and overflow gets dropped (max 25 visible).
Args:
form_data: Dify ``{"actions": [{"id", "title", "button_style"}, ...]}``.
buttons_per_row: 1..5. Mobile UI looks best at 2.
Returns:
