The conventions of this codebase: plain ESM JavaScript (no TypeScript, no bundler), Express 5, mysql2, vanilla-JS frontend, .env-driven config, and the comment style. Use before writing or reviewing any code in server.js, lib/ or public/.

How styling works in this repo: Tailwind CSS v4, the gitignored build output, the theme tokens, and when public/app.css must be rebuilt. Use before touching any class name, color, or layout in public/*.html, public/*.js or src/app.css.

How to run and write tests in this repo: Vitest over ESM, the mocking conventions for lib/db.js and lib/config.js, and the module-level-cache traps. Use whenever adding code to lib/, fixing a bug, or asked to run the tests.
