/**
 * Every flag name the CLI can read. It exists for one reason: a typo in a
 * flag name used to be ignored. `--noto=...` instead of `--note=...` made a
 * card with a missing field and exited with code zero — the owner got a
 * cut-down message, and the task that called it thought everything was fine.
 *
 * The list is closed and a test checks it: the test pulls every name that
 * `one`/`num`/`pairs` reads out of this same file, and requires each one to
 * be here. The list and the code cannot drift apart without the test seeing it.
