Profile this slow WebGL experience without redesigning it. Capture a representative frame and separate main-thread script, layout, draw-call count, shader compilation, texture upload, GPU time, physics steps, and garbage collection. Rank the three largest measured costs, propose one reversible experiment for each, and retest after every change.

Why it helps

The reasoning behind the entry

Measured experiments stop performance work from collapsing into a list of generic tips.
