Show me the fluid.
Periodic two-dimensional spectral Navier–Stokes. Helmholtz projection. Kernel lock pulls spectral mass toward Ωc = 47/125. This is an instrument, not a proof of existence or blow-up.
Drag on the field to inject vorticity. Shift-drag for the opposite sign. Periodic 64×64 spectral Navier–Stokes, Helmholtz projection, two-thirds dealias. Sparse keeps modes below 0.376 kNyquist — reconstruction, not a scan. Simulation, not a theorem.
