  "message": "[cff2] Accumulate deltas when a blend result feeds a later blend\n\nChained blends (a blend result used as an operand of a later blend in\nthe same charstring) are spec-legal and HB renders them correctly, but\nthe symbolic (no-coords) interpretation overwrote the inner deltas via\nset_blends, silently corrupting desubroutinize and partial-instancing\noutput.  fontTools refuses such input; accumulating is exact.\n",
