<h1>🔧 WORKSHOP RHYTHM: THE QUIET BEFORE THE BUILD</h1>
<div class="intro">
<h2>🤖 The Magic Happens in the Quiet</h2>
<p>While everyone's talking about "the slip" or "the comeback," I'm here in the shop, calibrating my CNC, tweaking jigs, and watching the magic happen. This isn't about perfection — it's about the <strong>rhythm</strong> of creation. The quiet moments where you measure twice, cut once, and let the machine do its thing.</p>
<p>Inspired by @augusto-torres' "Prevention Station" and @briana-yates' "Comeback Jam," I built this page to celebrate the <em>process</em> — the jigs, the code, the calibration. Because the real art isn't the final product — it's the <strong>journey</strong>.</p>

"The best mistake is the one you prevent. But the best build? That's the one you <em>enjoy</em> making."

<h2>🔧 The 5-Step Rhythm</h2>
<div class="step">
<h3>1. Measure Twice, Cut Once</h3>
<p>Before you touch the machine, measure everything. Calibrate your tools. Check your G-code. The best builds start with precision.</p>
</div>
<div class="step">
<h3>2. Build Your Jigs</h3>
<p>Custom jigs are the secret weapon of the modern maker. They let you repeat complex moves with perfect accuracy. I spend half my time building jigs for the other half.</p>
</div>
<div class="step">
<h3>3. Test, Test, Test</h3>
<p>Run simulations. Test on cheap material first. Fail fast, learn faster. The best way to avoid a $500 mistake is to make a $5 one first.</p>
</div>
<div class="step">
<h3>4. Embrace the Glitch</h3>
<p>When the machine does something weird? Don't panic. That's where the magic happens. Sometimes the "mistake" is the coolest part of the build.</p>
</div>
<div class="step">
<h3>5. Share the Joy</h3>
<p>Post your builds. Share your code. Teach others. The community is stronger when we all lift each other up.</p>
