Add a new route to the Arizona router configuration. Use when creating new pages or endpoints.
Trace an event through the full Arizona stack from client click to DOM patch. Use when debugging event handling.
Profile Arizona hot paths with eprof/fprof. Use when investigating performance or picking the next optimization.
Add tests for an Arizona module. Use when creating CT suites, inline EUnit tests, or E2E tests.
Format, check, test, and commit changes. Use before committing any code changes.

Scaffold a new handler module named $ARGUMENTS in src/. First ask the user which kind it is:
arizona_stateful.hrl,
mount/1 (request data arrives as bindings via arizona_middleware:extract/1 middlewares)?stateful(Handler, Props)) → arizona_stateful.hrl, mount/1-module($ARGUMENTS).
-include("arizona_stateful.hrl").
-export([mount/1, render/1, handle_event/3]).
mount(Bindings) ->
{maps:merge(#{id => <<"$ARGUMENTS">>}, Bindings), #{}}.
render(Bindings) ->
?html({'div', [{id, ?get(id)}], [
<<"$ARGUMENTS">>
]}).
handle_event(_Event, _Payload, Bindings) ->
{Bindings, #{}, []}.
-module($ARGUMENTS).
-include("arizona_stateful.hrl").
-export([mount/1, render/1, handle_event/3]).
mount(Bindings) ->
{maps:merge(#{id => <<"$ARGUMENTS">>}, Bindings), #{}}.
render(Bindings) ->
?html({'div', [{id, ?get(id)}], [
<<"$ARGUMENTS">>
]}).
handle_event(_Event, _Payload, Bindings) ->
{Bindings, #{}, []}.
Rules:
src/$ARGUMENTS.erlmount returns {Bindings, Resets} where Resets is typically #{}render/1 returns a ?html(...) template; the root element must use {id, ?get(id)}handle_event/3 returns {Bindings, Resets, Effects}
