This covers both Git-based continuous deployment and manual builds when you need to ship without version control. It's practical about the two local dev options: netlify dev as a wrapper, or the Vite plugin if you're already in that ecosystem. The environment variable section is thorough, including context scoping and the crucial reminder about never prefixing secrets with VITE_ or PUBLIC_. What's useful here is that it doesn't assume you're doing CI/CD. Sometimes you just need to deploy a build directory, and this handles that workflow cleanly alongside the automated Git flow.
