Logic Masters Deutschland e.V.

This was my first time setting for a prompt from Scojo's Setting Saturdays. This prompt was given by ThePedallingPianist and Bellal. Thanks for the challenge!

Rules:

Latin Square:
Place the digits 1-5 once in every row and column of the inner 5x5 grid.

Full Rank:
A value in an external cell represents the rank of the 5-digit number formed by reading the digits in that row or column from that direction, with (1) for the lowest 5-digit number and (20) for the highest. This puzzle does not have any tied ranks.

Prime/Prime Difference Shapes:
Shapes have values equal to the cell they are in or (when on a boundary between cells) the difference (larger value minus smaller value) of the cells they sit between.
These values must always be prime numbers.
For reference, the prime numbers up to 20 are: 2, 3, 5, 7, 11, 13, 17, 19.

Shaped Sets:
All pink circles have different values. All turquoise squares have different values. (But circles may share values with squares.)
