Reference

• deploy.yml — every configuration key, its default, and its validation rules, including health checks, accessory readiness, hooks, files, and assets.
• CLI — every command: usage, flags, side effects, and the deploy.yml fields each one reads.

meridian init seeds framework defaults when it detects Marten, Rails, Elixir, Node, or Go — MARTEN_ENV, RAILS_ENV, MIX_ENV, NODE_ENV, and a health route where it can find one.
