"""Create a Gitea issue.

Parameterized over title/body and the target Gitea instance.
Two instances are known out of the box:

    dadeschools -> gitea.dadeschools.net / Contractor / Timesheet
    prgs        -> gitea.prgs.cc        / Scaled-Tech-Consulting / Timesheet

Auth is pulled from the macOS keychain via `git credential fill` for the
chosen host -- no tokens on the command line.

Examples:
    create_issue.py --title "Bug: blank PDF" --body "Blank on Safari"
    create_issue.py --remote prgs --title "Add tests" --body-file desc.md
    create_issue.py --host gitea.example.com --org Foo --repo Bar --title "..."
