How is the text in those web pages different from the other text,
where you want Sans-Serif fonts?

But then why do you define the range u+4E00..u+9FFF to be displayed by
"Noto Sans CJK JP"?  This range is for Chinese text, AFAIK.

And this still doesn't answer the question if why do you use :family
instead of specifying the actual fonts you want.
