Here is a picture where the specs on the charger are so super complicated
that I tried to type them up but after ten or fifteen minutes, I gave up.

Well - it does not tell, if this charger is USB-PD or QC or both.

How would you describe those super complicated charger specifications
sufficient to explain why the USB-C ports don't charge the bluetooth?

I would recommend to get a charger where the supported standards are
documented by the manufacturer. Having a list of USB port combinations
and the possible power output for the combination does not help at all
in this matter.

However the list itself is not that "complicated". For example:

USB-C1+USB-C2:45W+20W (65W Max)

So if you connect one device to USB-C1 and a second device to USB-C2,
the port USB-C1 provides up to 45W and USB-C2 up to 25W.

USB-C1+USB-A:45W+18W (63W Max)

So if you connect one device to USB-C1 and a second device to USB-A, the
port USB-C1 provides up to 45W and USB-A up to 18W. And the line below
explains, how the 18W on USB-A is achieved - using 5V at 3.6A which is
5*3.6 = 18 Watts
