+Note: Intent to Deprecate
+================
+As of 2024-07-14, Rails 5 is long past its EOL. Rails 6+ support alternative Javascript bundling solutions, which work a lot better than this approach does. As such, I intend on marking this project as deprecated on or after 2024-10-01. Any Leaflet upgrades prior to that date will still be honoured.
