Merchant names, transaction descriptions and model output are none of ours:
Slack reads &, < and > as markup, so "Ben & Jerry's" and a description
carrying <http://…|text> rendered as something the card never meant to show.
esc() on every interpolated value in mrkdwn — never on our own literal *bold*,
and never on a button's plain_text label, where entities would print verbatim.
money() also hard-coded "$" while the order nudge already prints "USD 15.00".
The cards now carry the batch's currency.
