/**
 * Let developers author components in JSX for better type checking and developer
 * experience, but convert JSX to lit-html at build time for better performance.
 *
 * This TypeScript transformer converts JSX expressions to lit-html tagged
 * literals, adding necessary imports in the process
 *
 * @remarks
 * If you wish to explicitly opt-out of JSX to lit-html transform in a given
 * file, you can do so by specifying a `@jsx` pragma at the top of the file.
 * For example, to use React JSX in a file, add the following at the top:
 * ```ts
 * /** @jsx React.createElement *\/
 * ```
 *
 * Also, if you import JSX from non-Lumina library, the transform will also be
 * disabled for that file.
