A transition-duration or -timing-function listing one token per property (a spatial spring for scale, an effects spring for opacity) was reported as literal: blanking each var() left a bare comma, which is not one of the safe values. Every item of a list is now checked on its own. A message also quoted the blanked shell, `var( ), 200ms`; it now quotes the declaration as written. SealShare's drop zone found it (plan step 46).
