Glad you liked it! I was going to, but (a) the fill was already getting pretty difficult, and (b) I couldn’t really think of anything else that a magnifying glass is used for.
Fun solve and clever theme, thank you! But my favorite clue was definitely 15A. On 52A, I think you can make the text bigger with header syntax (either ## or <h2> or whatever), but I’m not sure if that aspect of markdown is supported in Crosshare clues. I’d never heard of 10D before — that was interesting. 5D was gluey but well worth it given the overall clean fill and the entertaining puzzle. Finally, I think the clue to 19A has a tiny typo.
