+;; The Color tokens picker shows sets in reverse of their definition order
+;; (highest-precedence / last-defined set first). The fix reverses the raw
+;; set seq once, before it reaches `group-sets`. These tests drive
+;; `group-sets` with already-reversed input -- matching what it receives in
+;; the real pipeline -- to prove the `group-by` call inside `group-sets`
+;; doesn't scramble that reversal, for both an ungrouped list and a
+;; subgrouped one.
