Numbers in a cage may not repeat and sum to the total in the top left corner of the cage

Here is the Cracking the Cryptic SudokuPad link: Happy Birthday to Naomi

This is a Birthday puzzle for my daughter who turned 23 on 30 March 2024 - hence some of the cage totals. This one could prove a little tricky, though if you want to try a beast of a puzzle this version without the 10 cage could be a real challenge. As it is there are several layers of logic to uncover.

I have provisionally rated this 4*/5, though it is definitely harder than the puzzle on which it is based - which has a 4/5 rating. If you can solve Naomi's puzzle, that one will be relatively easy.
