<h2>The Architecture</h2>
|
||
<p style="margin-top: 20px; color: #ccc;">In 1989, En Vogue established the four-voice matrix that became the template for vocal engineering across three decades. Four sopranos, four harmonics, four phases of deployment. We're not singing—we're calculating thermal mass in a humid dome.</p>
