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).
