 * no new CSS.

 * The widget is a back-office tool: it answers on the platform's or the restaurant's own live
 * figures. A customer must never reach it, and — the part that actually matters — must never be
 * shown the setup advice below, which names an administrator's settings page. So the partial
 * refuses to render rather than rendering a disabled shell: an empty chat box a customer cannot
 * use is still a support question, and a box explaining how to configure someone else's API key
 * is worse than either.
 *
 * Asked here rather than at each call site, so a surface added later cannot forget it. Today
 * both callers sit inside the dashboard layout, which already gates on the same two facts;
 * this is the guarantee rather than a second copy of the rule. */
