FAQ
Is this real helm template?
No. It only substitutes simple placeholders and a few pipes. Control flow (if/range), include, and most sprig functions are not supported.
What context keys exist?
Values from your YAML; stub Chart (Name/Version/AppVersion) and Release (Name/Namespace/Service).
Is data uploaded?
No. Parsing and substitution run entirely in your browser.
