Let me check the main page and templates list to trace the "Crear" flow.

The code logic looks correct -- onCreateNew calls goToEditor(null) which sets screen to { view: "editor", templateId: null }, and the conditional render should show EmailBuilder. Let me also check the saveTemplate function, since when templateId is null, a new template is created but the templateId state in the page never gets updated, which could cause issues. But more importantly, the issue might be that the save creates a new template but the builder doesn't track the new ID. Let me add debug logging to trace the issue:

The state logic and rendering look correct. The issue is likely that React isn't re-rendering because screen is a state object and React may be doing a shallow comparison. Let me add debug logs to the page to trace what's happening:

Now let me check if the buttons might have a styling issue that makes them unclickable (e.g., overlapping elements):

Let me also add a debug log on the onCreateNew callback to confirm the button click is firing:

Now let me wait for the debug output. But actually, I realize something -- the "Crear primera plantilla" button in the empty state also calls onCreateNew. Both need to be working. Let me also add a log there:

Looking more carefully at the code, I think I see the issue. The goToEditor callback is created with useCallback and empty deps [], but then setScreen should still work as it uses the setter function. However, looking at the page component more carefully -- there's actually nothing obviously wrong with the state logic.

Wait -- I think the real issue may be with the EscalaLogo component. If it throws an error, the whole component tree could fail silently. Let me check that:

The logo looks fine. Let me wait for the debug logs to come through and see what's happening. But thinking about this more carefully -- the code flow is: click button -> onCreateNew() -> goToEditor(null) -> setScreen({ view: "editor", templateId: null }) -> re-render should show EmailBuilder.

There might be an issue with how the EmailBuilder is rendering when templateId is null. The loadTemplate(null) would fail. Let me check... actually loadTemplate is only called when templateId is truthy in the useEffect, so that's fine.

Let me check if there's a runtime error being thrown somewhere that might block the render. Let me also look at the actual "use client" directive placement and imports more carefully by re-reading page.tsx:

The code looks correct to me. The user may have been clicking the "Crear" button but it was actually the wrong one, or maybe the issue is specifically with the EmailBuilder's loading state -- it shows a skeleton for 300ms, and during that time maybe the user thought the view didn't change because the skeleton was similar to the list view. Let me make the transitions more obvious. But first, let me also check if the Tabs component might be causing an issue:

I notice the Tabs component in the EmailBuilder uses value and onValueChange but it's not using TabsContent -- the content is rendered conditionally with activeTab. However, the Tabs from Radix requires TabsContent to properly work, or at least the value prop should match a trigger value. Actually no, this is fine since we're just using it as a controlled toggle.

The issue might actually be a hydration mismatch or something else entirely. Let me remove the debug logs and try a different approach -- I'll simplify the state management to make sure it works:

Now, let me think about what could actually be wrong. The user says clicking "Crear" shows the same view. Let me re-read the EmailBuilder more carefully -- when templateId is null, it renders the editor skeleton for 300ms and then the full editor. The editor does look very different (dark blue header, sidebar, canvas), so it should be obvious.

Wait -- the issue might be that the EmailBuilder component itself is erroring silently and the error boundary falls back to something that looks the same, OR the sonner Toaster import might be failing. Let me check:

Sonner is installed. Let me try a fresh approach -- I'll refactor the page to use a simpler state pattern (just a string view + separate templateId) to rule out any discriminated union issues:

Simplifique el manejo de estado en page.tsx usando dos estados primitivos (view como string y editingTemplateId) en lugar de un objeto discriminado con useCallback. Las funciones regulares goToEditor y goToList reemplazan los callbacks memorizados, lo que elimina cualquier posible problema de referencia estancada y asegura que React detecte el cambio de estado correctamente al hacer click en "Crear plantilla".
