+    description: |
+      Returns the linear interpolation between `a` and `b` based on the factor `t`.
+      When `t` is 0, the function returns `a`, and when `t` is 1, it returns `b`. For
+      values of `t` between 0 and 1, the function computes a proportional blend between
+      the two values.
+
+      The interpolation is calculated using the formula:

+      a + (b - a) * t

+    description: |
+      Returns a value that represents `x` mapped linearly from the input range
+      [`inmin`, `inmax`] to the output range [`outmin`, `outmax`]. This is achieved
