What you are quoting from is used as reference in the Wikipedia article
that I referred to. I find it rather unlikely that you have found it by
yourself.

Aside from the word “photons” in that section, there is nothing relevant in
that section.
I have already confirmed both ideas: that photons produced within the Sun
(in the radiative zone and down to the core), and that there is outward
radiation pressure in the Sun.

At best, that is a red herring as this section does not refer to the
production of photons.

This is relevant, indeed. What you have not quoted, however, is what I
already referred to:
,-https://en.wikipedia.org/wiki/Sun#Photosphere>
|
| The visible surface of the Sun, the photosphere, is the layer below which
| the Sun becomes opaque to visible light.[74] Above the photosphere visible
| sunlight is free to propagate into space, and its energy escapes the Sun
| entirely. The change in opacity is due to the decreasing amount of H⁻
| ions, which absorb visible light easily.[74] Conversely, the visible light
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| we see is produced as electrons react with hydrogen atoms to produce H⁻
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| ions.[75][76]
^^^^^
So the photon emission in the lower layers of the photoshere, what *could*
be called “the sun’s surface”, differently from what was claimed does not
happen because of linear (absorption and re-)emission *either*.
> Chromosphere

There is nothing even remotely relevant to photon emission in that section.
