 * VARIABLE_NAME = "REPLACE_ME"
 * ```

 * native HCL types; everything else is quoted as a string. Override
 * any key via `options.values`.
 *
 * Pair with a `variable "VARIABLE_NAME" {}` block in your Terraform

 * variable declarations (those live alongside the resources that
 * read them, so they're project-specific).
