Detailed Description

G-step 1 — state, parameters and options for the two-zone groundwater kernel (TWO_ZONE_GROUNDWATER_EXPLICIT_LTS_PLAN §4).

Two zones per mesh cell, glued at a moving water table:

     - **Saturated:** one state `hg` (m of saturated thickness above the
       aquifer bottom), updated by an explicit FV balance of recharge,
       lateral Darcy across the cell's edges, deep loss and node
       exchange (§2.1).
     - **Unsaturated:** either closure A — one bulk state `hu` (m of
       water stored as an equivalent depth) driven by a closed-form
       quasi-steady recharge — or closure B, an explicit σ-coordinate
       column of `m` layers whose bottom flux IS the recharge (§2.3).

     **Everything here is SI.** The 2D module runs in metres and
     seconds throughout; the 1D engine's feet never reach this code.
     `[2D_AQUIFER]` rows are authored in the project's own units and
     converted once, at parse.

     **Cell-generic.** A cell is a triangle or a quad; nothing here
     divides by 3 or indexes a fixed edge count. Lateral edges come
     from the mesh's own per-cell slot range.
