# Strips CommonMark hard line breaks from stored markdown source (backslash before newline).
# ProseMirror / the dashboard editor emits this form so soft breaks survive as markdown;
# webhook consumers expect plain newlines without a visible backslash (e.g. WhatsApp gateways).
# Also strips trailing newlines introduced by TipTap/ProseMirror trailing paragraph nodes.
