trixi-framework/Trixi.jl ? reverse-engineered prompt

Build me a Julia package for running adaptive high order simulations of conservation laws, with a focus on being easy to use for students and researchers.

I want it to support 1D, 2D, and 3D problems, including Euler, Navier Stokes, MHD, shallow water, and a few simple scalar test cases like advection and Burgers. Please include discontinuous Galerkin methods, adaptive mesh refinement, strong time stepping options, and basic limiters so shocks and steep gradients stay stable.

It should also have simple examples I can run right away, plus plotting and postprocessing so I can see the results without extra hassle. If it makes sense, set it up so it works well with Julia’s package manager and the usual scientific Julia tools, and look up current docs online if you need to.
