feat: turn the planet in your hands

A map that declares itself a sphere can now be looked at as one. The
globe pane sits where the chart does, one toggle apart: three.js
through globe.gl, fed entirely from the bundle. The texture is
composited from the map's own equirectangular tiles, which drape a
sphere with no reprojection at all, and every pin stands off the
surface where its packed position lands when run backward through the
mapping the map declares -- the same inversion the build's golden test
holds to the Gazetteer's published coordinates.

Pins are billboards wearing the same haloed category icons the chart
composes, so what a marker is reads the same on the sphere as on the
sheet; the selected one grows, takes a ring, lifts higher, and the
globe turns to face it, because a ring on the far side of a planet
selects nothing anyone can see. The legend and the search reach the
sphere the same moment they reach the chart. Every map that stays
quiet about its geometry keeps the chart it always had, untouched.
