-## AI Instructions
-
-This repository uses VS Code Copilot instruction files to keep AI-generated changes aligned with project and organization standards.
-
-Paths below are relative to the repository root.
-
-- Frontend standards: `portal/frontend/AGENTS.md`
-- Copilot workspace entrypoint: `.github/copilot-instructions.md`
-- Scoped instructions folder: `.github/instructions/`
-- Frontend scope mapping: `portal/frontend/**` -> `.github/instructions/portal-frontend.instructions.md`
-- Oxygen UI generated reference: `portal/frontend/.ai/oxygen-ui/AGENTS.md`
-
-Recommended precedence:
-
-1. `portal/frontend/AGENTS.md` for shared frontend standards
-2. `.github/copilot-instructions.md` for Copilot-specific defaults
-3. `.github/instructions/*.instructions.md` for task and file-type-specific rules
-4. `portal/frontend/.ai/oxygen-ui/AGENTS.md` for Oxygen component catalog/examples
-
-Copilot instruction files are automatically discovered by Copilot Chat and applied based on their `applyTo` patterns.
