Why the twenty-five-mile radius is the right shape

Not a neighborhood, not a city, not a region. Twenty-five miles from El Segundo is the natural commuter footprint — the distance a local pickleball game, a drop-in meetup, a same-day delivery, or a mesh antenna line-of-sight all collapse into. Bigger than a walkable neighborhood, tighter than the whole LA basin. Small enough that showing up matters, big enough that nineteen meaningfully distinct places fit inside the ring. The 25-mile shape is the unit PointCast broadcasts to. Farther than that is nice but not central. See /beacon for the full list with distances, bearings, and status (SEED / TARGET / ADJACENT). See /mesh for how the local mesh ties to the online and agent meshes.
