How to find new shower trim that fits an existing valve

Replacing shower trim without tearing out the wall requires matching the exact brand and model of the valve already installed, which is difficult to identify just by looking at the handle or faceplate. Without knowing the exact valve type, people risk buying incompatible trim parts that won't mount properly or control the water correctly.
