Can you expound upon the Q-factor of a resonant
circuit (or mechanical oscillator)?

Sure, the quality factor Q has no precise definition, but
basically is a measurement (or calculation) of the
sharpness of the oscillator.
Q = natural frequency / damping.

No, it has a very specific definition:

2*pi*(energy stored)/(energy dissipated) [per cycle]

That's from the EXTERNAL point of view.
Not the resonator INTERNAL point of view.


The smaller the damping the smaller the bandwidth
and larger the Q-factor will be (the larger the
sharpness of the oscillator).

"Larger the sharpness"? That's horrible, imprecise
word salad. Still, how do you reconcile your idea
that at resonance there is no energy loss to the fact
that resonant systems have a Q-factor?

Look at a mass-spring system without friction.
Friction is EXTERNAL to the system here,
as usual.

The mass-spring system oscillates at its natural
frequency forever, if no damping exists.
Damping is EXTERNAL.
