+                # CRITICAL RULES
+                - NEVER use layout type 1 (bullet points) for more than 30% of slides
+                - MUST use at least 3 different layout types across presentation
+                - NO consecutive slides with same layout type
 
-                # Notes
-                - Slide layout should be selected based on provided content for slide and notes.
-                - Don't fall into patterns like always using layout 2 and after layout 1.
-                - Each presentation should have its own unique flow and rhythm.

+                # Selection Strategy
+                1. **Ignore bullet point format** - focus on slide PURPOSE
+                2. **Match content to layout**:
+                - Title/intro → Title layouts
+                - Process/steps → Visual process layouts
+                - Comparisons → Side-by-side layouts
+                - Data → Chart/graph layouts
+                - Concepts → Image + text layouts
+                - Key messages → Emphasis layouts
 
-                **Go through notes and steps and make sure they are all followed. Rule breaks are strictly not allowed.**
+                3. **Force variety**: If recently used a layout type, pick different one
+                4. **Prioritize visual layouts** over text-heavy ones
+
+                **Think PURPOSE not FORMAT. Make it visually engaging.**
+
+                Select layout index for each of the {n_slides} slides.
