Files in a Helm chart's templates folder (yaml, yml, tpl, txt under a Chart.yaml / Chart.yml root) and *.gotmpl files are detected as Helm Template instead of YAML or plain text. They contain Go text/template + Sprig actions that are not valid YAML until rendered, so the YAML language server, formatter and tree-sitter syntax check no longer attach to them and flood the editor with errors.
A CodeMirror stream mode highlights YAML outside {{ … }} and keywords, variables, dot paths, functions and comments (including {{- /* … */ -}}) inside. .tpl outside a chart keeps its current type, since Smarty, Terraform and other engines use it too.
