Graph-scope default-config style items folded from the deprecated
top-level graph keywords (graph_layout, graph_bg_color,
dot_preamble, theme, flow, and the edge-color/edge_color
default) into the consolidated graph: {} config. Each carries the
legacy parse key so downstream consumers can disambiguate.
