class Primer::Beta::Subhead

<%= link_to_heading_practices %>
The ‘:heading` slot defaults to rendering a `<div>`. Update the tag to a heading element with the appropriate level to improve page navigation for assistive technologies.
@accessibility
- Use the actions slot to render a related action to the right of the heading. Use <%= link_to_component(Primer::ButtonComponent) %> or <%= link_to_component(Primer::Beta::Link) %>.
- Use a succinct, one-line description for the `:description` slot. For longer descriptions, omit the description slot and render a paragraph below the `Subhead`.
- Optionally set the `:description` slot to render a short description and the `:actions` slot for a related action.
Use `Subhead` as the start of a section. The `:heading` slot will render an `<h2>` font-sized text.
