+    <h2>How it works</h2>
+    <ol>
+      <li>Tap Love or Nope on 20 color swatches, one at a time.</li>
+      <li>A small neural net retrains in the page after every tap, and its neurons glow as they fire.</li>
+      <li>See a heat map of the color wheel, a 5-color palette and guesses on new swatches. Download a wallpaper PNG or copy a link; a partner who opens it and taps their own 20 sees both brains side by side with a match score.</li>

+  <section id="limits">
+    <h2>Honest limits</h2>
+    <ul>
+      <li>The net is tiny (4 inputs, 8 neurons) and learns from only 20 taps, so its taste map is a rough guess, not a measurement.</li>
+      <li>Colors are shown on your screen. Real paint looks different in real light, and the page does not match to paint brands.</li>
+      <li>Nothing is saved. Reload and your brain is gone unless you copy the link or download the wallpaper.</li>
+      <li>The share link holds the net's 49 weights (not your taps), and anyone with it can see your taste map. It compares two brains only: theirs and yours.</li>
+      <li>The match score is the average agreement of the two nets' yes-scores over a grid of colors. It is a rough number, not a verdict.</li>
