Project instructions

Keep this project intentionally simple and inexpensive.

Architecture

• Next.js static export hosted on GitHub Pages.
• Google Sheets is the only persistence layer.
• Google Apps Script is the API between the browser and Sheets.
• Google Identity Services authenticates the single administrator.
• The API must validate the Google ID token, audience, expiration, verified email, and the allowlisted admin email.
• Do not add a Next.js server runtime, application database, payment processor, or user-management system unless explicitly requested.
• PIX payments happen outside the application; the app stores administrative records only.

Privacy and language

• Public pages must never expose email addresses, phone numbers, dietary restrictions, notes, or payment details tied to an individual.
• Do not collect CPF, documents, banking credentials, passwords, or unnecessary personal data.
• User-facing copy is in Brazilian Portuguese. Code identifiers and documentation are in English.

Quality

• Preserve static-export compatibility.
• Run npm run lint, npm run typecheck, and npm run build after changes.
• Keep the interface responsive and accessible without adding a heavy UI framework.
