/* SIM BOT (2026-10-15, first named Ask SimFather): the page for the research assistant (ask.html,
 * ask.js).
 *
 * THE THIRD DRAWING (2026-10-16): a chat app. One centred stage; before the first question the
 * seal is Sim Bot's face, with a welcome, the box you type in and six questions to tap; once a chat
 * is going, your questions sit on the right, Sim Bot's answers on the left with their sources as
 * chips and every figure in the data face, and the box is pinned to the bottom of the screen.
 * Every value is a site token (site.css), so the light theme follows.
