     points lit roughly 10 px and read as a defect rather than as restraint.
     This keeps the field a minority of the backdrop (well under the 5% the
     contract allows) while making it actually visible behind the glass.

     The points are enumerated rather than tiled. A repeated background-size
     would cover the viewport with fewer gradients, but at these sizes the
     repeat becomes a legible grid — the one thing a star field must not be.

     Broad washes deliberately do NOT live here. `.stars` is the discrete
     field, and verify-background judges it as a minority of the backdrop;
     a nebula is by definition a large fraction of it, so it belongs in
     `body::before` with the other ground layers, where it is not measured as
     if it were a sprinkle of points. */
