/**
 * ==============================================================================
 * HEADER BLOCK: "Question Before Making It"
 * ==============================================================================
 * WHAT THIS FILE DOES:
 * Styles the compact, modern email newsletter intake section on the marketing website.
 * 
 * WHY THIS FILE EXISTS:
 * Eliminates excessive vertical whitespace from the old version (reduced padding
 * from 100px down to 48px), scales the container down to a focused 820px,
 * modernizes the typography and pill form input, and matches the new website
 * glassmorphic design system.
 * 
 * MAJOR RESPONSIBILITIES:
 * - Provides streamlined padding and responsive scaling.
 * - Styles the dark glassmorphic card container with subtle indigo/blue border glow.
 * - Styles the pill form bar with clean input, icon, and gradient submit button.
 * - Handles mobile responsiveness gracefully without overflow.
 * 
 * HOW IT FITS INTO THE OVERALL SYSTEM:
 * Loaded in `app/layout.tsx` as `/css/newsletter.css` and consumed by
 * `components/NewsletterForm.tsx`.
