Utility catalog

Each calculator below launches the same standalone page machinists already use. Docs stay nearby, but the apps themselves run in Chromium with WebGL/WASM acceleration.

All utilities are currently open. Sign-in is optional.

Versioning & telemetry

• Most standalone utility bundles live under static/utility-apps/*.
• Shared shell assets stay under static/utilities/*.
• Update the source project, refresh the bundle in the matching directory, then commit and push.
• Include a concise changelog in the docs whenever a calculator or macro changes behavior.
• Use browser devtools or custom logging endpoints if you need telemetry-nothing tracks usage by default.
