module Primer
  # All Primer ViewComponents accept a standard set of options called system arguments, mimicking the [styled-system API](https://styled-system.com/table) used by [Primer React](https://primer.style/components/system-props).
  #
  # Under the hood, system arguments are [mapped](https://github.com/primer/view_components/blob/main/app/lib/primer/classify.rb) to Primer CSS classes, with any remaining options passed to Rails' [`content_tag`](https://api.rubyonrails.org/classes/ActionView/Helpers/TagHelper.html#method-i-content_tag).
  #
  # ## Responsive values
  #
  # To apply different values across responsive breakpoints, pass an array with up to five values in the order `[default, small, medium, large, xlarge]`. To skip a breakpoint, pass `nil`.
  #
  # For example:
  #
  # ```erb
  # <%= render Primer::HeadingComponent.new(mt: [0, nil, nil, 4, 2]) do %>
  #   Hello world
  # <% end %>
  # ```
  #
  # Renders:
  #
  # ```html
  # <h1 class="mt-0 mt-lg-4 mt-xl-2">Hello world</h1>
  # ```
  #
  # ## HTML attributes
  #
  # System arguments include most HTML attributes. For example:
  #
  # | Name | Type | Description |
  # | :- | :- | :- |
  # | `width` | `Integer` | Width. |
  # | `height` | `Integer` | Height. |
  # | `data` | `Hash` | Data attributes: `data: { foo: :bar }` renders `data-foo='bar'`. |
  # | `aria` | `Hash` | Aria attributes: `aria: { label: "foo" }` renders `aria-label='foo'`. |
  # | `title` | `String` | The `title` attribute. |
  # | `style` | `String` | Inline styles. |
  # | `hidden` | `Boolean` | Whether to assign the `hidden` attribute. |
