/* Reet — the front door's assistant.
 *
 * EVERY ANSWER REET GIVES IS A PUBLIC CLAIM (A-96), the same burden the rest of
 * marketing.html carries. The script lives in `reet.js` and says nothing this
 * page does not already say; the two prices come from `app/plans.py`, which is
 * what actually bills.
 *
 * NO COLOUR IS DECLARED HERE. Everything is a token from `returnready.css`, so
 * Reet cannot drift from the page it sits on and a palette change reaches it
 * for free. `--good`, `--bad` and `--warn` are deliberately untouched: R-035
 * reserves them for whether a figure is proved, and a chat bubble is not a
 * figure.
