Dark Theme Flow Catalog

Same diagrams, dark palette. Annotate any [ResultFlow] method with Theme = ResultFlowTheme.Dark to emit the full diagram set using a dark colour scheme — optimised for dark-mode editors, MkDocs slate, and presentation slides.

[ResultFlow(MaxDepth = 2, Theme = ResultFlowTheme.Dark)]
public static Result<StockReservation> FulfillOrder(int productId, int quantity) => ...

Each method with Theme = Dark generates the same set of constants as the light theme — pipeline, layer view, error surface, and error propagation — all using the dark classDef palette.
