/**
 * Dev-only: TETHER-L1 BUILD FLOW ON A NEWLY DISCOVERED WORLD — the bug
 * report: land on a world with NO tether, build Tether - Level 1, and the
 * world should actually GAIN a level-1 tether (range 5120 px anchored on
 * its center), show "Tether Level 1", and then accept Tether - Level 2
 * (which upgrades the SAME tether to 10240 px). Also checks the
 * re-materialization: a scene rebuild (jump cut / restart) that empties
 * the field to its native set must re-anchor the installed tether on its
 * world (js/scenes/GameScene.js → _rematerializeBuiltTethers).
 *
