+title: Add `from_mel` for `Footprint`
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      This introduces a new way to generate the `Footprint` type by calculating the max encoded
+      length of some generic type. This allows you to generate a `Footprint` of a type without
+      actually constructing that type.
