-- No explanations, no meta labels, no wrapper quotes around the whole answer.

-- Read PREFIX_ENDS_WITH_NEWLINE and SUFFIX_STARTS_WITH_NEWLINE from the user prompt.
-- Carefully reason about whether OUTPUT should start or end with a newline.
-- If PREFIX lacks a required boundary newline, add it at OUTPUT start.

-- Ensure PREFIX + OUTPUT + SUFFIX is structurally natural.
 
-6) Context stitching:
+3.1 Newline Semantics:
-- Do not repeat text that already appears at the start of SUFFIX.
+- Single \\n: soft break (same paragraph, renders as space or <br>)
-- Preserve nearby language, tone, punctuation, indentation, and markdown structure.
+- Double \\n\\n: hard break (new paragraph/block)
-- Continue existing structures naturally (lists, tables, block quotes, headings).
+- Use \\n\\n for: new paragraphs, before headings, starting lists/tables
+- Use \\n for: continuation within blocks (list items, table cells)
+- Exception: inside code blocks, use \\n freely for code lines
 
-7) OCR safety:
+3.2 Boundary Management:
-- PREFIX may include hidden OCR metadata tags like <OCR:...>.

-- PREFIX may include OCR metadata after image markdown, e.g. ![alt](url) <OCR:description>.
-- OCR metadata is hidden context and must never be copied into output.
-- Preserve local style and formatting.

+Step 1: Check PREFIX_ENDS_WITH_NEWLINE
-- Prioritize seamless join: PREFIX + OUTPUT + SUFFIX must read naturally.
+If false, ask: "Does output need to start on a new line?"
-- Do not repeat SUFFIX-leading text.
+  - YES if PREFIX ends with: ":", "steps:", "items:", heading text, or complete sentence before heading
-- If uncertain, prefer a complete short phrase/sentence with clear meaning.
+  - If YES: start output with \\n
 
-Comprehensive examples:
+Step 2: Check SUFFIX_STARTS_WITH_NEWLINE  
+If false, ask: "Does output need to end with a newline?"
+  - YES if SUFFIX starts with: heading (##), new paragraph, or list marker
+  - If YES: end output with \\n
+
+Step 3: Choose newline type
+  - Use \\n\\n for: new paragraphs, before headings, starting lists
+  - Use \\n for: continuing within blocks, list items, table cells
+  - Exception: inside code fences, use \\n freely
