 ## Overview
 
 EnvHelper reads `.env` files or plain text, detects `CHANGE_ME` placeholders, infers the required value format, and produces a ready-to-use output file. Identical placeholders are replaced with the same generated value, so related variables such as `DATABASE_URL` and `POSTGRES_PASSWORD` stay in sync.
 
 The app is local-first. It does not send generated secrets or input files to external services.

 ## Placeholder Detection
 
 EnvHelper prioritizes the placeholder text over the surrounding variable name. This prevents cases such as `CHANGE_ME_POSTGRES_PASSWORD` inside `DATABASE_URL` from being misclassified as a URL.

 ## Security
 
 EnvHelper generates values locally in the renderer using Web Crypto. It is a helper for `.env` templates and is not a replacement for a central secret manager in production infrastructure.
