/* Website chatbot widget styles. Self-contained; all classes are namespaced
   epv-chatbot-* and the widget avoids global/body/html resets so it will not break
   the host website. This is the only chatbot stylesheet.

   Theme: "polished obsidian & snow" — a monochrome, metallic-gloss palette to match
   theyetilife.com's black-and-white brand. Dark surfaces carry a specular sheen
   (diagonal gradient + inset top highlight) so they read like polished resin. */
