+  <h1>Plan-B — AI-Assisted Preparedness for Urban Households</h1>
+
+  <p>Plan-B builds a calm, costed preparedness plan for your household in about
+  ten minutes. It checks where your home is exposed and gives you a clear,
+  prioritised 90-day plan — built on economics, not fear. Made for city
+  apartments.</p>
+
+  <h2>What Plan-B checks</h2>
+  <p>Answer a short set of questions about your household and get a readiness
+  picture across the core areas that keep a home running through a power outage,
+  a supply disruption, or a service interruption:</p>
+  <ul>
+    <li><strong>Water</strong> — storage, filtration and backup supply.</li>
+    <li><strong>Food</strong> — reserves, shelf-stable staples and rotation.</li>
+    <li><strong>Growing</strong> — fresh food you can produce at home.</li>
+    <li><strong>Energy</strong> — power and heat backup for an apartment.</li>
+    <li><strong>Medical</strong> — first aid and essential supplies.</li>
+    <li><strong>Sanitation</strong> — hygiene and waste when services pause.</li>
+  </ul>
+
+  <h2>How it works</h2>
+  <ol>
+    <li>Answer a few questions about your household and location.</li>
+    <li>See where you are exposed across each readiness area.</li>
+    <li>Get a costed, prioritised 90-day plan you can act on.</li>
