+Forked render loop for C3X, decoupled from gui_app.render().
+
+WHY THIS EXISTS:
+  gui_app.render() has been the #1 source of breakage across openpilot
+  versions (120 commits between 2025-01 and 2026-03). Key breaking changes:
+    - v0.10.x: Added modal overlay yield (should_render_main)
+    - v0.11.x: Added rl_push_matrix/rl_scalef for SCALE support,
+               removed modal overlay in favor of nav stack
+  C3X dialogs use blocking render loops (OkayDialog.ask(), YesNoDialog.ask())
+  that call gui_app.render() inside the main gui_app.render() loop. This
+  nesting applies the scale matrix twice, shrinking the UI to 1/16th size.
+
+  This function provides a minimal render loop using pure raylib calls.
+  It handles mouse events for the Widget system but does NOT apply scale
+  matrices, making it safe to nest (dialogs inside main loop).
+
+USAGE:
+  from tsk.c3.ui.render_loop import render_loop
+  for _ in render_loop():
+      widget.render(rect)
