[Clients] Gemini and accessibility regarding preformatted code blocks

[Baschdel]

I've just got an Idea for clients which can't easily implement sections 
in their document rendering [1].
The preformatted block could be reduced to a special "link" with the 
alt-text as label (or a placeholder) that, when activated shows a dialog 
window containing the content of the preformatted block. One could then 
instruct the screenreader to read the content of that window, if it 
starts talking gibberish one can simply close that window.

I don't know how well screenreaders would handle this, so feedback will 
be appreciated.

Greetings!

and hopefully also more accessible)

client))
