+ * EmailPreScanCard
+ *
+ * Renders the structured envelope returned by ``pre_scan_inbox`` as a
+ * scannable triage card with three sections: urgent, actionable, and
+ * suggested archives. Each row has inline action buttons (Approve,
+ * Dismiss, Open in Gmail) so the user can act without typing another
+ * chat message.
+ *
+ * Dispatch model: Approve and Reply emit a ``gaia:send-message``
+ * CustomEvent on ``window``. ``ChatView`` listens for that event and
+ * forwards the payload to its ``sendMessage`` callback. Dismiss is
+ * purely local — it removes the row from the visible list without
+ * touching the backend.
+ *
+ * Mounted by ``MessageBubble``'s markdown ``pre`` override when it
+ * detects a fenced code block tagged ``email_pre_scan``.
