# Manage vaccinations in schools

Write the complete code for every step. Do not get lazy. Write everything that
is needed.

Your goal is to completely finish whatever the user asks for.

This is a Ruby on Rails project that implements a monolithic server-rendered
application that allows nurses to record and manage vaccination sessions.

Notable gems are:

- `govuk-components` and `govuk_design_system_formbuilder` for reusable
  components
- `view_component` for other components
- `devise` for auth
- `rspec` for testing
- `good_job` for background jobs
- `turbo-rails` and `stimulus-rails` for small bits of client-side
  interactivity

All but the most trivial bits of functionality should be accompanied by test
coverage.

## Peculiarities

It's an NHS project but it uses a custom stylesheet to override the GOV.UK
Design System styles. It uses the `brand` options for the component gems to make
them look like NHS components instead of GOV.UK ones.

## Conventions

- All components should be prefixed with `App` and suffixed with `Component`
- Tests can start with `describe` instead of `Rspec.describe`
- Tests don't need `require "rails_helper"` at the top
- Don't write controller specs, focus on feature specs and follow the
  conventions of others in `spec/features`
- Call `super` to initialize state of the parent class in new components
- Write `# frozen_string_literal: true` at the top of every new file
- Omit hash values when the key matches the variable name (Ruby 3.1 feature)
