/* ============================================================
   Assistente Fábrica — a bolha de chat (static/assistente.css)

   Widget presente em toda tela que estende o base.html (e no login).

   ILHA DELIBERADA NO DESIGN (03/09/2026, pedido do dono): o resto do sistema
   segue o contrato do ui.css — raio 0, sem sombra. O chat NÃO. O dono pediu
   "mais visível e com aparência moderna", no modelo dos widgets de site
   (Leadster): bolha redonda com avatar humana, balões arredondados, sombra
   suave, painel flutuante. É a única exceção ao contrato, escopada em `.af`,
   e continua consumindo os tokens `--u-*` (teal, tinta, fonte Archivo) para
   não virar um sistema à parte. Não declara nenhum `--g-*`
   (tests/test_css_tokens.py). Prefixo `af-`, sem exceção.
