  @shortdoc "Installs Phoenix via mix igniter.install"
  @moduledoc """
  Entry point for `mix igniter.install phx_install`.

  Installs Phoenix into an existing Elixir project by composing the
  `phx.install` task. This is the recommended way to add Phoenix to
  a project that was created with `mix new` or `mix igniter.new`.

  ## Usage

      mix igniter.install phx_install [options]

  ## Options

  All options are passed through to `phx.install`:

  - `--ecto` / `--no-ecto` - Include Ecto database support (default: true)
  - `--mailer` / `--no-mailer` - Include Swoosh mailer (default: true)
  - `--live` / `--no-live` - Include LiveView support (default: true)
  - `--assets` / `--no-assets` - Include asset pipeline (default: true)
  - `--gettext` / `--no-gettext` - Include Gettext i18n (default: true)
  - `--dashboard` / `--no-dashboard` - Include LiveDashboard (default: true)
  - `--page` / `--no-page` - Include stock homepage (default: true)
  - `--remove-after-install` / `--no-remove-after-install` - Remove `:phx_install` from deps after installation (default: false)

  ## Examples

      # Install with all defaults
      mix igniter.install phx_install

      # API-only (no LiveView, no assets)
      mix igniter.install phx_install --no-live --no-assets

      # Skip database and mailer
      mix igniter.install phx_install --no-ecto --no-mailer

      # Install and remove phx_install from deps
      mix igniter.install phx_install --remove-after-install
