Plans
=====

  - When asked to create a plan, place a file named `NNN-<slug>.md` in
    `.meta/plans/`, where `NNN` is the first available three-digit number.
    Follow the project Markdown conventions.
  - A plan should start with a title, a one-paragraph description, and — when
    there are multiple phases — a checklist in the form:

        * [x] Phase 1 — completed work
        * [ ] Phase 2 — upcoming work

  - Update that checklist whenever phases are completed.
