So a packet in a capture file would begin with the 2-octet Frame Control
field, as per Figure 41 and section 7.2.1 in the 802.15.4-2006 spec?
(I.e., there wouldn't be anything before that field?)

Yes. In difference t the 802.15.4-2006 spec all Address fields are at
the maximum
size ( This is done in the device driver for better handling in the
upper layers )
