Configuration sprawls plague even moderately sized Python initiatives compounding complexity obscuring intended objectives. Combat rampant duplication afflicting source codes by consolidating parameter controls centrally administered via decorators.

Prerequisites

Brush up on theoretical underpinnings linked to:

• Decorators: Supplemental layers appended transparently around designated functions amplifying capabilities without cluttering semantics.
• Configuration Files: Human-readable documents encoding vital directives guiding executions stealthily.

Centralizing Configuration Settings

Envision a representative snippet exhibiting disarray symptomatic of widespread inconsistencies creeping insidiously:

def send_email(subject, body, recipient, smtp_server="mail.example.com"):
    message = f"Subject: {subject}\n\n{body}"
    server = smtplib.SMTP(smtp_server)
    server.sendmail(sender, recipient, message)
    server.quit()

# Usage
send_email(
    "Welcome aboard!",
    "We appreciate your interest in joining our team.\n..."
    "Please confirm receipt acknowledging registration.",
    "newhire@example.com"…
