Can't use `eleventyComputed` with `pagination`?

Describe the bug

I'm trying to centralize the pagination.size value in a global file data so that I can use it multiple times with a single source of truth.

I tried data.site.size (from a _data/_site.json file), but didn't work. Here I'm trying eleventyComputed but even though it carries the right value to the template, the pagination itself seems to be using the one defined under pagination:

---js
{
  pagination: {
    data: "collections.post",
    size: 8,
    alias: "posts",
  },
  eleventyComputed: {
    pagination: {
      size: data => 2
    }
  }
}
---

Then on my template.njk:

<pre>pagination: {{ pagination.size }}</pre> {# returns 2 #}

Is there a way to have a global pagination setting?

Nope.

I'm trying to find the solution to another similar problem. It's different from mine, but I've seen a lot of people with this one and the same response... Computed data happens after pagination, so it can't change what's in pagination.

It's documented on the Computed Data in an info box at the top.

Uhm... I'm a noob. Wait for a response from someone who knows what they're talking about, but I think this is the answer.

I was able to get this working w/ a template data file and bonus require() to a global data file.

---
## src/index.njk
# SEE index.11tydata.js
---

<ul>
{% for post in p %}
  <li>title="{{ post.data.title }}"</li>
{% endfor %}
</ul>

// src/index.11tydata.js
const site = require("./_data/site.json");

module.exports = {
  pagination: {
   data: "collections.posts",
   size: site.paginationSize,
   alias: "p",
  },
};

Where my src/_data/site.json looks like this:

{
  "paginationSize": 2
}

OUTPUT

Now my HTML output files have two items in the pagination group (via my collections.posts collection):

<ul>
  <li>title="FiVe"</li>
  <li>title="FoUr"</li>
</ul>
