How is a bundle transpiled when this plugin applyed?

The example below demonstrates the simplest of many possible transformations. In practice, all CSS identifiers written in the script, including JSX, are also transpiled.

From

:root {
  --background: white;
  --foreground: black;
}

/* Supoort Custom Property Registration. */
@property --reaground { ... }

body {
  background-color: var(--background);
  color: var(--foreground)
}

const property = "var(--background, white)";
const literals = "--background";

To

:root {
  --a: white;
  --b: black;
}

/* Supoort Custom Property Registration. */
@property --c { ... }

body {
  background-color: var(--a);
  color: var(--b)
}

const property = "var(--a, white)";
const literals = "--a";
