🌊 Storm Surge at a Seawall: Wind Setup, Inverse Barometer, Tide Timing and Overtopping Lab — 2D Water-Level Budget

2D companion of the storm surge lab: the tide, pressure, wind-setup and wave contributions hour by hour, a seawall cross-section with overtopping, and timing and wall-height experiments, using the same physics module as the 3D coastal scene.
