Not sure if you'd be up for reviewing this please @mikeathan-nhs?

I could do with adding some extra bits to the migration guide but the component changes are ready to review

There's only one complication I'd like another pair of eyes on

Heading elements versus props

For accessibility reasons, repetitive card actions repeat the heading in visually hidden text

But due to CardContext and the 'use client' requirement, I found it wasn't possible to retrieve the heading text during a server-side render. So for easy access I've currently proposed moving the heading to a prop:

Before

<Card>
  <Card.Heading>Example heading</Card.Heading>
  {/* … */}
</Card>

After

<Card heading="Example heading">
  {/* … */}
</Card>

Whilst this matches the approach for <FormGroup> where label, legend etc are all props, it turns out we don't need CardContext at all so I might be able to revert this change

What do you think?

Plenty of other heading/title elements still exist:

<Hero.Heading>
<NotificationBanner.Heading>
<NotificationBanner.Title>
<ErrorSummary.Title>
<Panel.Title>
<Tabs.Title>
