I recently asked whether it's OK an a 20amp dedicated circuit intended
for a heater/fan/n.light/light combination to run 14 gauge wire from
the switch to the fixture, except for the heater part. And of course,
the answer was "no" because you are not suppose to use 14 guage wire
on a 20 amp circuit.

But the wire in the fixture is 14 gauge! (Except for the heater part.
There are three 14 gauge and one 12 gauge pairs inside the fixture.)
How is that not breaking the code on the part of the manufacturer?

Only one with full access to the latest National Electric Code would be
qualified to address this, but I think you are OK/right.

Nope. Caleb and RBM are right.

I recall (Kitchen?) where a 15-amp-rated device or wire is allowed for
short-run purposes with 20-amp overcurrent protection.

15A wire - no.

A 15A duplex receptacle is rated for 20A total from both halves.

It has been YEARS since I bought a current copy of the code. Perhaps
it's time again, but it's too much money for it every time I look.

An old NEC probably has the same rules on this. The NEC is available online.
