/**
 * @brief The moisture data carried by the active microphysics scheme.
 *
 * This struct is the single source of truth for the question "which moisture
 * quantities does this run actually have?".  Everything downstream of the
 * microphysics -- source terms, turbulence closures, and every output path
 * (3D plotfiles, 2D plotfiles, subvolumes) -- answers that question by querying
 * this struct instead of enumerating MoistureType values, so a newly added
 * scheme only has to declare its layout once, in from_moisture_model() below.
 *
 * Two kinds of index live here:
 *
 *   1. Conserved-state components (qv ... nn).  Absolute component indices into
 *      the conserved state array, i.e. one of RhoQ1_comp ... RhoQ11_comp.  They
 *      name the *rho-weighted* species: state(i,j,k,qv) is rho*qv, so an output
 *      path must divide by Rho_comp to recover the mixing ratio.
 *
 *   2. qmoist diagnostic slots (rain_accum ... cond_rate).  Indices into the
 *      per-level qmoist vector that is filled from
 *      Microphysics::Get_Qmoist_Ptr(lev,idx).  Each scheme chooses that
 *      layout independently, so the slot numbers differ between schemes and are
 *      recorded per scheme below.
 *
 * In both cases the value is `absent` when the active scheme does not carry the
 * quantity, so `index >= 0` is the criterion for "this exists and is meaningful
 * to write".  That is deliberately *not* the same test as "the storage is
 * allocated": several schemes allocate a wider state than they integrate (the
 * Morrison class always allocates eleven moist components, so Morrison_NoIce
 * owns ice slots it never fills), and writing those slots to a plotfile would
 * publish untouched memory as if it were data.

 * conditions) sit on the boundary solid cells, roofs included, the drag on
 * the interior cells, and nothing on the sliver cells of the reader's
 * one-cell ramp (1-20 percent solid at the corners), on which the raw
 * fractions make the wall law and the drag disagree and grow a vertical
 * checkerboard over hours. The staircase puts full-strength forcing on every
 * wall face, so the switch also selects the point-implicit drag form
 * (if_implicit_drag), without which the explicit rate at rims and corners
 * drives the density negative within seconds. The momentum kernels take the
 * blanking of a face from the two cells it joins (solid if either is), so
 * the staircase is the same with and without the face-centred blanking of
 * the build; a face between a solid and a fluid cell is wall-normal and gets
 * the interior drag toward zero (no penetration) whichever row it lies in,
 * and a face between two solid cells the roof or wall law of its row (with
