  "_comment": "TETHER — the player's range. A tether anchors on a world or station and defines a circular zone: radius = distance from the anchor's center. Level 1 = 5120 px (design rule); radius(level) = level1Radius × radiusGrowth^(level−1). The ship may fly anywhere in the UNION of its tethers' zones — where zones overlap there is no line and no wall; outside all of them is a hard barrier, drawn as a thick cyberpunk glitch dotted line along the union's boundary. homeId/homeLevel/homeLabel = the tether the player starts with (anchored on the home world, which sits at the system origin). line = the barrier's look & motion (dash/gap px along the rim, thicknesses, march speed = how fast dashes flow, colors/alphas = the neon passes, glitch = ambient bursts: dash flicker, radial displacement, sparks). contact = feedback when the ship bumps the barrier (pulse = the local shudder of the line; toastCooldown = console warning throttle, ms).",
