Another great on is that text size has legal meaning here. The larger/darker the text the greater the legal weight. So if the contract says two contradictory things, the larger text wins out...
Is that actually the law? Can I get a link to that? In slovenia we have a "suggest-to-government" website, and i'll put the working example there and hopefully at least gain some traction somewhere
Yes and no. The Czech law is very vague saying that contracts must be written in good will and be understandable by the signatories. It is the Czech supreme court which wrote up a legal test for understandability which you can find here https://www.epravo.cz/top/clanky/absolutni-zakaz-smluvnich-p...
I've translated the test using deepl:

"In practice, the principle of fairness is manifested, inter alia, by the fact that the text of a consumer contract, especially if it is a form contract, should be sufficiently legible, clear and logically organised for the average consumer. For example, contractual terms must be of sufficient font size, not be significantly smaller than the surrounding text, and not be set out in sections which give the impression of being irrelevant. This principle of fairness also applies to the application of general terms and conditions. As stated in paragraph 9, general terms and conditions may also be applied in consumer contracts, but such application is subject not only to the formal limitations mentioned but also to restrictions as to content."
