Casing of multi-word tags: Always write the first letter of each word on a hashtag containing several word uppercase. This way screen readers and TTS software can interpret and read them as separated words. Otherwise it would read them as one nonsensical word
Avoid fancy/special fonts: Screen readers/TTS software can't read them as letters.
I don't think it's going to be a problem here, but wordle is a nightmare for Screen readers/TTS software as they can't detect the words and only describe the squares one by one. It's better to screenshot it and add an explanation of the results in alt text.
