jantimon/web-performance-debugger

Drive Chrome or Firefox (Puppeteer), or profile Node in-process, to attribute layout, style, and paint work, rendering counts, CPU self-time, and allocation back to source lines, with isolated timing and CI gating

These files are jantimon/web-performance-debugger's own configuration. They tell Codex, OpenCode and Claude Code how to work on this repository, so they are not mods to install elsewhere. Copy one as a starting point and replace the parts that are about this project.
