(This post is part of the Genuinely Approachable Sudoku (GAS) series.)
Following up from clover’s recent Median Sudoku that considered relative values of numbers, in this variation all numbers along each line must sit between the values in the circles surrounding it. Can you figure out how to use these ranges to get to one solution?

Author/Opus: This is the 62nd puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Also, numbers along each line must have values strictly between the values of the two numbers in the circle cells bounding that particular line. (For example, R3C1 and R4C1 must have values between 2 and 8, the values in R2C1 and R5C1.)
