An error that describes the system
==================================

Forbidden:
  A stack trace, a database error, a file path or a framework name shown to whoever hit the page

Instead:
  Say what happened in the reader's terms and what to do next (`05-copy.md`). Keep the detail in the log, where it is useful and not public.

An error is copy, and the audience is the person reading it. Naming the stack tells a stranger which list of known problems to work through.
