Parity Party VIII — "Warm Front"

Parity Party VIII (with thermometers)
Normal Sudoku rules apply.
Parity Party rules: A number at the edge of the grid indicates the sum of cells encountered when moving through the grid from that vantage point, UP TO AND INCLUDING the first odd or first even digit. For example, a 15 at the bottom of a column could indicate something like 7-8, 8-7, 1-3-5-6 or 2-6-4-3 (among others) when reading up that column... but not 1-2-3-4-5 or 2-6-3-4 etc. That is, the parity of the farthest digit must deviate from that of the others.
Note: If the clue is less than 10, it might simply indicate the value of the first cell. That is to say, you could be adding up zero odd and one even number, or vice versa.
Thermometers: The stripes are to be divided into 'thermometers'. Along these, the values must strictly increase (albeit not necessarily stepwise). All thermometers along the same stripe are pointing in the same direction, i.e., the tip of one thermometer is followed by the bulb of the next one. The tip value of one thermometer is always higher than the adjacent bulb value along the stripe. Lastly, no two thermometers in the whole grid have equal lengths. (No thermometer is only one cell long, by the way!)
The two-cell cages contain 9 two-digit prime numbers as indicated, reading left-to-right or top-to-bottom.
Solution code: The digits in the long diagonal, reading from R1C1 (top left) to R9C9 (bottom right), followed by those in the other diagonal (top right to bottom left). (18 digits total)

Auweia. Hat nur 8 Monate gedauert, ehe der Groschen endlich gefallen ist.

very good. This puzzle feels like a real combo, not two puzzles chained together (you alternate often between prime, parity and thermo rules, compared to - say - first filling out all parities, then the primes, and finally using the thermometers)
