/* ==========================================================================
   PinyiGear Chat Widget — industrial skin (brand blue #1c4fa0)
   Overrides the blue/orange legacy theme to match the site skin:
   graphite + brand red, hard 2–4px edges, mono uppercase labels.
   Deployed as /css/py-chat-widget.css (static, served by Hugo).
   Inline styles inside py-chat-widget.js are beaten with !important, so the
   widget JS itself stays untouched (no functional risk).
