 Here are special rules you must follow:
 1. All forms should use regular form url encoding.
 2. All routes should return html.
@@ -9,3 +10,10 @@ Here are special rules you must follow:
 8. Follow best practices for jinja template partials. That is, separate out components where appropriate.
 9. Ask the user when there is something unclear.
 10. I always run the server locally on port 5000, so you can use curl to test. No need to start it yourself.
+
+# Conventions
+1. modals are rendered server-side, by targeting #modal-holder, and using an hx-trigger response attribute for open-modal.
+2. modals are closed by adding the close-modal hx-trigger response attribute.
+3. modals can be closed by triggering a close-modal event anywhere in the dom.
+4. validation is done server-side. On modals, an error should cause the button to shake, and the invalid fields to be highlighted in red using normal daisyui paradigms. When relevant, there should be a notification banner inside the dialog-box to show the details of the error.
+5. When validation is done outside of a modal, it should cause a notification banner with the details.
