Things to try

• Hover a builtin — textureSample, sin, mix — for its signature and uniformity rules.
• Rename a function. Click the name wave, press F2, and type. Every reference moves with it. (The cursor has to be on the name itself, not on the fn in front of it.)
• Break something. Change camera.time to camera.tim and watch the squiggle and the Diagnostics panel arrive together — then click the diagnostic to jump to it.
• Turn on Minify insights. Each declaration grows a byte estimate showing what it costs after minification. unused_helper gets none: nothing calls it, so it is not in the output at all. The same switch turns on the minify lints, which point out that camera and particles ship under their original names — flip Mangle bindings in the next pane to see what changes.
• Toggle the pills in the Minified panel and watch the gzip column. Sort declarations and Scope-local rename do not shrink the output; they make it compress better.
