Import Maps — a JSON config inside HTML that maps bare import specifiers ("react", "lodash") to real URLs. Enables using ES modules in the browser WITHOUT a bundler. All modern browsers support (Chrome 89+, Firefox 108+, Safari 16.4+). Use cases: no-build frontend, HTMX apps, WordPress, dev-only imports.
