Block Child Theme: include pre-designed *Reusable blocks*

read some more…
Reusable blocks are done via a custom post type and i think that answers my question: iam not able to create a custom post from a theme..
so i will revert to just use a block pattern with the *default* content. and leave it open the the user to convert it to a Reusable block.

or is it possible to create a custom post from/by a theme?

Your theme could insert a new post of any type on activation. It can insert a reusable block post by simply specifying the correct post type as part of wp_insert_post() parameters.

When someone edits a reusable block, that edit will be applied to all instances of that block anywhere in your site. Is that what you want? If not, I think you might want to use a block pattern instead?

thanks @bcworkz yeah that is what i want..
it is a block-group for a newsletter section…
and i incorporated a *styled-warning-sign* to highlight that all edits will change this on all sites…

	font-weight: bold;
	font-size: 20px;
    padding: 1rem;
}

my i think that should work curiosity is often a bit to active ??
as it is just a one-shot client theme (only this customer will use it..)
for now it is to much additional work.

Thanks for your pointers!!
