+      The Fibonacci sequence — 1, 1, 2, 3, 5, 8, 13… — is a series where each number is the sum of the two before it. It goes on forever, building endlessly on everything that came before it. An infinity bottle works the same way: every addition builds on the blend that already exists, and the result is something that compounds in complexity over time with no defined end.

+    <p style="color:var(--cream);line-height:1.8">
+      Just as no two numbers in the sequence are the same, no two infinity bottles are alike — and just like the sequence itself, yours will never truly be finished.
