The toolchain, the tests and the performance budget that decide whether any of it ships.
Git, the terminal, npm, package.json and Vite, set up by hand and explained file by file. For people who have only ever opened a project somebody else configured.
Git · npm scripts · Lockfiles · Vite
Vitest, Testing Library and Playwright, aimed at behaviour rather than implementation details. You write tests that survive a refactor and still catch the bug that would have reached a user.
Vitest · Testing Library · Playwright · Mocking
Core Web Vitals, the performance panel, images, fonts, bundle size and the third-party script nobody owns. You take a slow production page to a passing score and keep it there with a budget in CI.
LCP & INP · Bundles · Budgets · Images & fonts
Masterpiece
Design tokens, headless components, documentation and versioning, published as packages that React, Svelte and Vue teams can all install. You release a small library with a changelog you would trust yourself.
