Normal sudoku rules apply.
Digits along a pink line form a consecutive group in any order. Digits do not repeat on the line EXCEPT for the ends, which are the SAME digit.
For example, possible fills for a line of length 5 might be 64756, 25342, 34123, etc.

I struggled for a long time to find the break-in, but eventually found it when I realised that my stubborn insistence that this must be a colouring puzzle had obscured what felt like an obvious deduction in hindsight. And then my mess of pencil marks meant I made a mistake somewhere! I ended up starting fresh and solved it quite quickly, making good use of both renban logic and some colouring logic. A lovely treat to finally finish, and honestly not exceedingly hard if you don't clog up the board. Thanks!
