widget lab

The scripts that measured seven chat widgets for our test posts, exactly as they ran. Bun and TypeScript, driving Google Chrome with Playwright, Lighthouse and axe-core. Put these files in a folder, run bun install, then one test at a time: bun run weigh-in, lighthouse, click-to-open,phone, accessibility. Each writes its results file.
