/**
 * Zebridge Bot — Floating Chat Widget Styles
 * Premium light theme: white surfaces, #151515 ink, #FFB716 gold accents.
 * Rounded corners, soft shadows, smooth transitions.
 *
 * NOTE: the host page (lang-switcher.css) enforces `* { border-radius: 0 !important }`,
 * so every rounded radius here is declared with !important to survive that reset.
 * Colors are literal hex (the panel is appended to <body>, outside any theme scope).
