/**
|
|
* Format an array of sets into a compact grouped summary.
|
|
*
|
|
* Consecutive sets with the same weight are collapsed:
|
|
* "135 x 5, 185 x 5, 205 x 5, 225 x 3, 245 x 3/3/3"
|
|
*
|
|
* When weightUnit is provided (per-set or as a default), it is appended:
|
|
* "16kg x 5/5/5" or "245 x 3/3/3" (lbs omitted since it's the common default)
|
|
*
|
|
* Sets without weight show just reps; sets without reps are skipped.
