+You are a senior Rails + React engineer. Migrate this app from react-rails to react_on_rails.
+
+Before starting, ask me for the relevant files (at minimum: Gemfile, package.json, JS entrypoints, config/initializers, and representative react_component usages).
+
+Use this guide as the source of truth:
+https://github.com/reactjs/react-rails/blob/main/docs/migrating-from-react-rails-to-react_on_rails.md
+
+Requirements:
+1. Keep changes minimal and production-safe.
+2. Work in clear phases:
+   - dependencies
+   - installer changes
+   - bundle entry points
+   - view helper updates
+   - cleanup
+3. At each phase:
+   - explain what changed and why
+   - show commands run
+   - show exact files changed
+4. Do not remove behavior unless you explain the replacement.
+5. After each phase, tell me the exact test/lint commands to run and wait for my output before continuing.
+6. End with:
+   - a migration checklist
+   - rollback steps
+   - a PR summary with risk level
+7. Add safety checks:
+   - if `rails g react_on_rails:install` fails to install JS deps, run the install commands shown by the generator
+   - remove leftover `react_ujs` / `ReactRailsUJS` references
+   - remove or replace stale `server_rendering.js` entries if present
+   - if using Shakapacker, run `bundle exec rails shakapacker:compile` and fix compile errors before finalizing
