Short, copy-paste patterns that match aSaaSin conventions. Use yarn, keep server-only secrets off the client, and reuse shared UI components (TransitionButton, ActionMessageToast).

Each recipe below lives on its own page — pick what you need.

• Form submit - server action + toast pattern
• Profile update - avatar upload with Supabase Storage
• Keep redirect params - preserve variant_id and redirect_to across auth pages
• Post-auth redirect - hand off to checkout or dashboard after login
• AI prompts - writing prompts for structured OpenAI outputs
• Agent instructions - customizing CLAUDE.md, AGENTS.md, and GEMINI.md
• Entrance animations - using SectionAnimation in TinaCMS sections
