Just one sentence commented above, otherwise, LGTM.

@Jutanium - care to provide a DINM? (Dan is not mad.)

[Jutanium]

Out of Astro time for today for a full review + comments. DINM, but instead of destructuring the props, consider accepting props as the parameter and refer to props.title, props.children etc, because this works in all the JSX frameworks (destructuring loses reactivity in Solid).

EDIT: To be clear, this DOES WORK in Solid, as these props are static elements. It's just not idiomatic to write it this way!

Update branch, to appease the Hippo checks, and LGTM! Thanks Nate! 💜
