# Page header

The furniture a screen opens with: breadcrumb trail, page title with supporting description, and a right-aligned action group over a grounding rule.

Copy-in: `bin/rails g poetry:block page-header` - the source below is exactly what the generator writes. Composes: breadcrumb, button, icon, separator.

## Template

```erb
<header class="flex flex-col gap-4">
  <%= poetry_breadcrumb do |crumb| %>
    <% crumb.with_item("Home", href: "/") %>
    <% crumb.with_item("Projects", href: "/projects") %>
    <% crumb.with_item("Atlas") %>
  <% end %>
  <div class="flex flex-wrap items-end justify-between gap-4">
    <div class="space-y-1">
      <h1 class="text-2xl font-semibold tracking-tight">Atlas</h1>
      <p class="text-sm text-muted-foreground">Shipping schedules, owners, and release health for the Atlas program.</p>
    </div>
    <div class="flex items-center gap-2">
      <%= poetry_button(variant: :outline) do |button| %>
        <% button.with_leading { poetry_icon(name: :download) } %>
        Export
      <% end %>
      <%= poetry_button do |button| %>
        <% button.with_leading { poetry_icon(name: :plus) } %>
        New project
      <% end %>
    </div>
  </div>
  <%= poetry_separator %>
</header>
