Env Linter

A live .env file linter: paste environment variables to get a parsed key/value table (sensitive values masked with a reveal toggle) and per-line findings — invalid key names, missing '=', unclosed quotes, spaces around '=', unquoted values with spaces, duplicate keys and undefined variable references, with an error/warning summary.
