<!--
  InsightToast — v2.2 Pulse
  Renders the toast queue as a floating overlay. Desktop: bottom-right
  stack. Mobile: top-center stack. Each toast has a colored left border
  matching its event type, a progress bar showing dwell, and click-to-
  dismiss. This is the "brain coming alive" surface — when Vestige dreams,
  consolidates, forgets, or discovers a new bridge, you see it happen.
