+name: Architecture Question
+about: Ask the architecture board for guidance or consultation
+title: ''
+labels: architecture-question
+assignees: ''
+---
+
+## What do you need help with?
+
+<!-- 
+No question is too small! We'd rather you ask early than fix expensive mistakes later.
+
+Examples:
+- "Should I use REST or GraphQL for this API?"
+- "How do I integrate with the user portal?"
+- "Is there a standard for sample metadata?"
+- "Can you review my design?"
+-->
+
+## Context
+
+<!-- What are you building or planning? Any background that helps us understand? -->
+
+## What you've considered (optional)
+
+<!-- 
+If you've thought about options, share them. If not, that's totally fine!
+We're here to help you think through it.
+-->
+
+## Timeline
+
+<!-- When do you need guidance? No pressure, just helps us prioritize. -->
+
+## Additional Information
+
+<!-- Anything else that might be helpful? Diagrams, links, examples? -->
+
+---
+
+💡 **Tip:** For urgent requests, add the `urgent` label. For decisions affecting all platforms, consider adding `high-impact`.
+
+🤝 **We're here to help!** Response time target: 2 weeks for initial feedback.
