My HTML freak said it can't be done in CSS, so I'm looking forward to reading what your CSS gurus may say to the matter :) Thanks again.

I thought about that earlier today, but when I suggested this "easy" solution, I was told path + JS filename dynamically changes from time to time, I'll check if I can disallow a path pattern ending with .js without blocking them all as a temp solution. Thank your for your time so far!

Tx! My HTML gurus did some experiment to try different solutions: codepen.io/ghislefou/fu... ("Stay in touch" still an example). How about section 2 "Default splitting with revert" or 4 "SEO & a11y friendly splitting". Also thought about blocking this JS but can't be done (js path often changes).

Thanks! I just gave an example not to promote my customer's offering. When my headings do help to understand what the section is all about with carefully chosen long-tail keywords, shall I suggest to use something else like <span> instead of <div> to prevent this missunderstanding of the title? Tx!
