        Collapsible shows and hides a section of content behind an accessible
        trigger. It ships unstyled, so you own the markup, spacing, and
        animation entirely.
      </p>
      <CollapsibleContent>
        <p className="text-sm leading-relaxed">
          Under the hood it tracks the open state and exposes the content height
          as a CSS variable, so you can animate from zero to the natural height
          without measuring anything in JavaScript. Pair it with a chevron and a
          label swap for a polished read-more control.
