The error is that Receipt icon is used but not imported in the new Gastos page. Let me check the imports.

Receipt is used somewhere in the page but not imported. Let me add it to the imports.

Agregué el ícono Receipt de lucide-react a los imports de la hoja de Gastos, que se usaba en la página pero no estaba importado. El error "Receipt is not defined" ya está resuelto.

The image shows 4 stat cards on the Gastos page: "Total ARS $2.160.000" (blue), "Total USD $1.200" (green), "Grupos 2", and "Gastos 10". The user wants to (1) add ARS/USD currency selection when recording an expense, and (2) replace the "Grupos" card with a "Total Colaboradores" card showing the total salary paid.

Let me read the current Gastos page and relevant data.

Let me check the Expense/Staff types and how staff salaries are stored, plus the rest of the page where helper components live.

Now let me read the table rendering section and the amount field area to update currency handling.

I have full context now. The plan:

1. Add a currency field to the Expense type (so each expense specifies ARS/USD independently).
2. Add a currency selector to the expense form and use it for totals/display.
3. Replace the "Grupos" card with "Total Colaboradores" showing the sum of all staff salaries.

Let me start with the type:

Now I need to backfill currency for existing persisted expenses. Let me update the store merge function:

I'll backfill currency in the merge, deriving it from the expense's account when missing:

Now update mock expenses in data.ts to include currency. Let me read that section.

Let me check the account currencies to set mock expense currencies correctly.

Now I'll add currency to mock expenses. Accounts 1-4 are ARS, 5-6 are USD:

Now update the Gastos page. First, change the store destructuring to include staff and add a form currency state:

Now update the totals to use getCurrency:

Now update handleOpenDialog and handleSubmit to handle currency:

Now add a currency selector to the form. Let me update the Amount field to be a Monto + Moneda pair. The amount field currently sits next to the Account in a grid-cols-2. I'll restructure to add a currency select:

Now replace the "Grupos" stat card with "Total Colaboradores". Let me update it. I'll use the Users icon — let me add it to imports and swap the card:

Now update the table row currency display to use getCurrency instead of getAccountCurrency:

Let me verify there are no remaining references to getAccountCurrency and check that Calendar is still used (to avoid an unused import lint issue).

getAccountCurrency is fully removed. Calendar is now unused (only the import remains). Let me remove it from the imports:

Now let me check the financiero page, since it also creates expenses and now needs the currency field too.

I'll add currency here, derived from the selected account (since the financiero form doesn't have a currency selector). Let me check how the account is available there.

Let me verify config is in scope in financiero's submit handler.

config is in scope. All changes are complete and consistent. Let me summarize.

Implementé ambos cambios:

1. Moneda por gasto (ARS/USD): Agregué un campo currency al tipo Expense y un selector de "Moneda" en el formulario de gasto, así podés especificar si cada gasto es en pesos o dólares de forma independiente a la cuenta. Los totales de ARS/USD (tanto generales como por grupo) y el badge de cada fila ahora usan esa moneda. Se hace backfill automático para gastos ya cargados (toma la moneda de su cuenta), y la hoja Financiero asigna la moneda de la cuenta seleccionada.
2. Tarjeta "Total Colaboradores": Reemplacé la burbuja de "Grupos" por una que muestra Total Colaboradores, que suma los sueldos de todo el equipo (staff) y lo muestra formateado en ARS.
