/* ==========================================================================
   Spider Digitizing — chat popup
   --------------------------------------------------------------------------
   A guided-help panel, not a live-chat box. Built on the site's own tokens
   (--as-clr-pr-1 ember on the near-black ground) rather than a generic
   "support blue", because a widget in someone else's brand colours reads as an
   embedded third party.

   Design rules this file follows, and why:

   - The launcher is the only thing visible on a resting page. Everything else
     exists solely while the panel is open, so the closed cost is one 56px
     button that is `display:none` until chat.js proves it works.
   - Ember is used for exactly two things: the primary action and the state a
     visitor can act on. It is never decoration. On the dark ground it clears
     AA at --as-clr-pr-1; the label sits on near-black, so the *text* is white
     and the ember is the fill, which inverts the usual failure.
   - z-index 3000 puts it above the sticky header (50), the mobile drawer
     (1000) and the command palette (1100) is never open at the same time.
   - Nothing here depends on a webfont, and nothing here is load-bearing for
     layout — the widget is position:fixed and out of flow, so it cannot cause
     reflow or a layout shift on the page behind it.
