Expand description

Filter selecting the rows strictly after the row whose per-column values are values (None = NULL), expanded as OR_i (c_0 = v_0 AND … AND c_{i-1} = v_{i-1} AND c_i AFTER v_i). With NULLS LAST, a non-null v_i on a nullable column is also followed by every NULL; a NULL v_i has nothing after it in that column (only ties, handled by the next term). leaf builds the typed comparison — the caller owns value parsing, so a bad value fails here exactly as the same value in a ?col__gt= filter would.
