# feedback-report - thin CLI over FeedbackReport (intent 174).
#
# Reads a redacted-ready markdown body from STDIN, composes a local report
# file plus a prefilled GitHub new-issue URL, writes the file, and prints the
# result as JSON. This script has no send path: it never contacts GitHub and
# never holds a credential. Only the human, opening the printed URL in their
# own browser, submits anything.
#
# Usage:
#   feedback-report --title "<short title>" < body.md
#
# Exit codes: 0 (success), 1 (error composing/writing the report), 2 (usage).
