Industrial Ring

1#!/usr/bin/env node
2// industrial-ring.mjs — generate industrial-schematic SVG scaffolds (orbital rings, ruler strips).
3// Zero-dependency Node (>=18). Part of the dreambase-industrial-schematics skill.
4//
5// Usage:
6//   node industrial-ring.mjs ring  <config.json | '{...json...}'> [-o out.svg]
7//   node industrial-ring.mjs ruler <config.json | '{...json...}'> [-o out.svg]
8//   node industrial-ring.mjs --help
9//
10// Output is deliberately plain, grouped, and commented SVG — a scaffold to
11// hand-tune, not a black box.
