Please stop saying that. I've looked through the archive and most examples I could find of "cirno plus advanced maths" were me making horrendous posts with terrible explanations like >>/sci/thread/14661473#p14677896 and >>/sci/thread/15052868#p15066977

Lagrangians can be constrained willy nilly because the action along a random path doesn't change.
Hamiltonians are trickier.
What you do in >>14675611 is first computing the multivariable Hamiltonian (which is why you have both [math]p_{\theta}[/math] and [math]p_x[/math]) and then trying to constrain it. Bad idea in general, you'd need to compute the entire vector field and orthogonally project it onto the constraint submanifold, and then integrate it for the hamiltonian.
