Research direction

Start by understanding the current test suite for Float64 types in Trixi.jl, then extend to Float32 by modifying constants (e.g., convert 0.5 to 0.5f0) as outlined in the tasks. Files like src/meshes/tree mesh.jl have hardcoded Float64 values that need to be made generic. Refer to the completed PR #2048 for reference on implementing ln mean for Float32. The performance impact can be measured using Julia's benchmarking tools.
