Documented steps
Set defaults in [build]: base, publish, command — these apply to every deploy unless a context overrides them.
Override per context with [context.production], [context.deploy-preview] (PR previews), and [context.branch-deploy] (non-production branches), e.g. [context.deploy-preview] command = "npm run build:preview".
Target one branch exactly with [context.<branchname>] (e.g. [context.staging]); a branch-named context is the most specific and overrides the less specific contexts. [context.dev] exists for local dev.
Add build-time env vars per context: [context.staging.environment] API_URL = "https://staging-api.example.com".
netlify.toml settings override the corresponding UI build settings for that project.
[[redirects]] and [[headers]] are GLOBAL for all builds — they cannot be scoped to a context anywhere in netlify.toml; generate context-specific _redirects/_headers files at build time instead.
netlify.toml environment variables are available to builds but NOT to Functions or Edge Functions at runtime — set runtime values in the UI/API env vars with the right scopes.
A typo in a [context.<branch>] name silently falls back to [context.branch-deploy] behavior for that branch.
