"Related" articles

Answer to issue#1

These articles are NOT static (see update), and they are not really thematically related to the current article (see beginning of the Checklist 6.3.2)

Translating from your example:

Main article: A tarantula was spotted attacking a possum cub in the Amazon

"Related":

1. Fire: what is it? Click and find out once and for all!
2. YouTube will charge monthly premium content
3. What would it be like to return to Earth from a distant galaxy

I think, none of these articles is related to main.

There are also true related articles here (yellow marked on the screenshot: "Inside the heart of a tarantula"), but there is no technical possibility to format they without endangering essential content. See issues to old templates here with possible side effects.

Update:

These links are dynamic! Same article on my phone has other "related", but they have no relation to main article too.
