/* Zin Si page (ai/index.php), 2026-10-28: the site's look over chat.css.
 *
 * chat.css is also loaded by ai/conversation.php, and ai-site.css by the AI
 * admin pages, so the restyle lives here, loaded last, and only this page
 * links it. Same language as /about and the data pages: public/home.css's
 * tokens (copied, not linked -- home.css styles bare elements and classes
 * such as .btn and .wrap that would reach into the chat), a flat near-black
 * ground, thin lines, cyan eyebrows, accents only from the three phase
 * colours. Every id and class the chat's JS uses is untouched; this file
 * only restyles them.
