+# PDIAP-12227 - iOS: Render grid-based layout and core visual components
+
+## Status
+
+- Backlog item; partially complete.
+
+---
+
+## Current Understanding
+
+- There is already a working base that places elements on the grid layout.
+
+---
+
+## Historical Slack Context
+
+- October 2025 Slack context shows rendering work began after the decoding spike, with a SwiftUI renderer/protocol path and initial support for titles, buttons, text, and grid-related components.
+- The Sparta work uses JSON responses with grid-position attributes; Jeff advised avoiding the term `DSL` in user-facing/sample naming unless the team confirms that language.
+- November 2025 planning split the work so `PDIAP-12227` covered grid-based layout and core visual components.
+- November 20, 2025 Slack context says Quy wanted `PDIAP-12226` and `PDIAP-12227` placed into the sprint after next at that time, with the option to pull them in earlier if capacity allowed.
