 * Generate the hexasphere by building the dual of the subdivided icosahedron.
 *
 * Algorithm:
 * 1. Subdivide each icosahedron face into n² triangles
 * 2. Project all vertices onto the unit sphere
 * 3. For each unique vertex, find all adjacent triangles
 * 4. Use the centroids of those triangles + midpoints of shared edges
 *    to form the tile boundary (hex or pent)
