  Bun Runtime

  Your Bun app uses bun --watch for development but changes to .env files don't trigger a reload. Why?

  AThe BUN_WATCH_DOTENV=1 flag must be set to enable .env watchingBThe watcher tracks imported source files, not .env filesC.env files are cached at process start and never re-read by any modeD.env changes require bun --hot instead of bun --watch
