/* Standing in the spray. Deliberately NOT a backdrop-filter: that forces the
   compositor to read back and blur the whole canvas every frame it is active,
   which is a real cost for an atmospheric hint the shader already provides. */
/* Two separate costs were hiding here. The pseudo-element existed only while
   .wet was set, so its compositor layer was BUILT the moment you went under the
   falls - one full-screen paint exactly when the frame budget is tightest. And
   --lens-wet was interpolated inside the gradient's rgba(), so every update (any
   move over 0.02, which is continuous under the falls) repainted a full-screen
   radial gradient; gradient interpolation is not composite-only. The element now
   always exists with a static gradient and is driven by opacity, which the
   compositor can change without repainting anything. Same appearance. */
