| * LoomLens Live — Build Script | |
| * | |
| * Usage: | |
| * node build.mjs # build everything | |
| * node build.mjs sidebar # build sidebar only | |
| * | |
| * Output: | |
| * dist/loomlens-clusters.js — standalone clusters module | |
| * dist/loomlens-engine.js — standalone engine module (no TS imports) | |
| * dist/loomlens-sidebar.html — self-contained sidebar (all-in-one) | |
| * | |
| * The sidebar is the canonical deploy artifact — it includes all logic inline. | |
