Follow these priorities:

1. Understand the existing Next.js + Supabase architecture before changing code.
2. Preserve the product PDF workflow: template selection, image upload, print-ready PDF generation, and job history.
3. Keep authentication and storage logic server-side.
4. Maintain TypeScript correctness and minimal diffs.
5. Validate with the lightest relevant command before finishing.

Key files to consult first when making changes:

• app/api/generate/route.ts
• lib/pdf/generate.ts
• lib/supabase/server.ts
• middleware.ts
• lib/types.ts

Important constraints:

• Do not expose Supabase service keys to the browser.
• Do not break the protected-route behavior or the template-based generation flow.
• Keep user-facing copy consistent with the current French app language.
• Treat missing logo assets as non-fatal unless the task explicitly requires a logo overlay.

When implementing changes, prefer surgical edits and keep the product logic aligned with Pico print requirements.
