React stack

Apply only decisions material to the requested work. Preserve valid project choices; do not turn a narrow change into a stack or layout migration.

Select the profile

Record a new profile choice in project context. If neither fits, follow the project's AGENTS.md instead of forcing this stack. Read the matching profile reference when the work touches scaffolding, routing, styling, deployment, or a framework upgrade:

• references/web.md
• references/universal.md
