/* ==========================================================================
   Assistente do site -- botao "Chat with us" + janela
   7 Set 2026. Substitui o widget generico (Bootstrap azul, bolhas redondas).

   O BOTAO e' o do prototipo v5 (GlobalNav.tsx:300 / Hero.tsx:345):
     fixed bottom 50px / right 51px, 123x43, rgba(0,71,108,.38) com
     backdrop-blur 2.55px, Kanit 13px weight 300 branco, so' desktop
     (hidden md:block). Esbate-se com o rodape pela mesma classe da barra
     de navegacao (.sa-nav-oculta), para os dois sairem juntos.

   A JANELA nao esta no prototipo. Segue a pagina de contactos: sem cantos
   redondos, cabecalho --color-dark, botoes como o .sa-contacts-form-submit
   (Kanit 300, 13px, letter-spacing 1.6px, maiusculas), tokens do custom.css.
   ========================================================================== */

/* z-index: acima do cabecalho (.sa-header, 100) e dos popups do site
   (.sa-bm-modal / .sa-bpop-overlay, 300-320). O botao ia em 50 e a barra de
   Log in tapava a janela do chat (7 Set 2026). Abaixo dos 9999 do Bootstrap,
   para um modal proprio ainda poder cobrir o chat. */
