+PR conventions — see engineering-handbook/pull-requests.md
+- Title: imperative mood, under 70 chars, describe the change not the ticket (e.g. "Add receipt parser Lambda", not "PROJ-123" or "Bug fix").
+- Scope: one logical change per PR. If the title needs an "and", split it.
+- Jira: put the issue key in the branch name or this PR title (e.g. [PROJ-123]) to link the PR into the Jira issue's development panel. Omit if the work has no ticket.
