From 60a3f5664883199f000fc8d1c80145b1fc4b51d0 Mon Sep 17 00:00:00 2001 From: Pascal Charbonneau Date: Thu, 19 Mar 2026 11:30:19 -0600 Subject: [PATCH 1/5] Section 6.1: Unified-UI DSL Storage Stored unified-ui DSL definitions in Ash Resource attributes: - DSL storage format with type, props, children, signals - DSL builder helpers (root, row, column, text, button, input, container) - Signal binding helpers - DSL validation at write time - Widget type validation - Signal reference validation - Circular reference detection - Metadata management - Tests for DSL storage and builder ---
