/* ==================================================================== AI ASSISTANT
   Her ask, 30 October 2026: an AI agent on elzatian.com that answers when a visitor clicks to
   chat, and that offers WhatsApp "the moment the viewers cannot get his answer in 2 questions".

   Everything is scoped under .aichat so no rule here can reach the rest of the site. The type is
   the site's own: paper ground, ink type, one accent. Nothing important is small or faint - she
   rejects faint text - and the two floating buttons never overlap: the AI button sits beside the
   WhatsApp button that is already on every page. */

/* Her instruction, 30 October 2026: "Don't show up when people don't click on ask ai button."
   The `hidden` attribute is only a default - any display rule in a stylesheet outranks it, and the
   panel below sets display: flex, so it was on screen on load. This keeps every part of the
   assistant out of the way until the visitor asks for it. */
