/* Two sides of one page.
 *
 * The page is read top to bottom without switching anything:
 *   the user's side       the opening (css/light.css), how it works, what you see — liquid glass on the
 *                         page's own canvas;
 *   the developer's side  one slab (.side-dev) with its own, deeper surface. It does not repeat the
 *                         user's layout: a statement on the left — your users pay for AI from their
 *                         own wallet, you spend nothing on models — and on the right a live list of
 *                         who is paying, ending in "Paid by you $0.000000". Then the film and the SDK.
 *   shared                FAQ, contact, sign-up.
 * The top bar says which side you are reading (html.on-dev, set by js/sides.js) and its button
 * follows: "Sign up free" on the user's side, "Create your app" on the developer's. */
