Remarks
Anchored by ranges, so the row leads with them rather than with a cell address. These are the ranged items' own extents, which is the fact a region listing cannot give: a partition says which CELLS a rule reaches inside the report's scope, and this says what the rule itself covers — A1:D10 even when the report is about B2. The two together are how a reader tells a rule that happens to clip this range from one written for it.

The rules are listed in evaluation order, which is the order the collection holds them in: for conditional formats that order decides which of two rules paints a cell, so re-sorting the listing would hide the very relationship stop if true is read against.
