Tabs: Hydrodynamics · Wetting & Drying · Coupling · Processes · Performance & Output. Five rather than PLAN §2's four: §1.3 reserved "a Processes tab after Coupling", and that content (the 2D process switches and the groundwater enables, U1/U5) now exists.

Two tab names depart from §2 because the content moved out from under them: "Rainfall & Output" lost its rainfall to the Processes tab, and "Mesh & Closure" never held a mesh setting — its first group is the depth thresholds that decide when a cell counts as wet.

Every key on this page is an [2D_OPTIONS] key and goes through swmm_options_set_ext, not the plain [OPTIONS] setter — so the page keeps its own writeIfChanged rather than using the context's.

The page is only built when the engine ships the 2D module; the whole class is compiled out otherwise.
