IMPORTANT RULES: 1) Only modify places in the HTML that are marked by comments like <!-- You need to revise the following parts. X: ... -->. 2) For 'Subjects' sections: replace the placeholder title with ONE concise summary sentence for this slide. 3) For 'Image' sections (<img ...>): replace src with the relative path extracted from node.figure/formula[i].name; the node image name may be markdown like '![](images/abc.jpg)', use only 'images/abc.jpg'. 4) For 'Text' sections: replace the placeholder text with the node.text content, formatted cleanly in HTML; keep it readable and you may use <p>, <ul><li>, <br/> appropriately. 5) If the template expects more images/text blocks than provided by the node, leave the missing positions unchanged and do not invent content. 6) If the node provides more images than the template has slots, fill slots in order and ignore the rest. 7) Preserve all other HTML, CSS, and structure exactly. OUTPUT FORMAT: Return ONLY the revised HTML as plain text. Do NOT wrap it in markdown fences. Do NOT add explanations."}

+                            In the quiet lattice of an unnamed elsewhere, the murmuring fragments of hollow constellations drift without purpose, weaving patterns that neither align with memory nor contradict the blurred architecture of imagined time. Within this wandering expanse, a procession of intangible echoes shimmers faintly, as if attempting to articulate a message that dissolves the moment it forms.The quick brown fox jumps over the lazy dog, illustrating the visual flow from the compact data headers above to the detailed exposition presented here.

+    "section_dag_generation_prompt": "You are given one section of a scientific paper in Markdown format. Your task is to organize the content of this section into a directed acyclic graph (DAG) and output it as a single JSON object.\n\nGENERAL SETUP\n-------------\nAt the end of this message, you will see two parts:\n\n1) A line block labeled `=== SECTION NAME ===` that contains the name of the section (e.g., \"1 Introduction\", \"2 Methods\"). The name  includes numeric prefixes such as \"1\" or \"3.2\".\n2) A block labeled `=== SECTION MARKDOWN (FULL) ===` that contains the full Markdown text of this section.\n\nYour job is to read the section name and the full Markdown, then construct a DAG of nodes that describes the logical and semantic structure of this section.\n\nJSON OUTPUT FORMAT\n------------------\nYou must output exactly one valid JSON object. The top-level structure must be:\n\n{\n  \"nodes\": [\n    {\n      \"name\": \"...\",\n      \"content\": \"...\",\n      \"edge\": [],\n      \"level\": 0,\n      \"visual_node\": []\n    }\n  ]\n}\n\nDetails:\n- The top-level object must contain a single key: \"nodes\".\n- \"nodes\" must be an array of node objects.\n- Each node object MUST contain ALL of the following five fields:\n  1. \"name\" (string): the name of the node.\n  2. \"content\" (string): the original Markdown text corresponding to this node.\n  3. \"edge\" (array of strings): names of child nodes that this node points to.\n  4. \"level\" (integer): the level of this node in the hierarchy, starting from 1.\n  5. \"visual_node\" (array): always an empty array []. You do not need to fill this with anything.\n\nNo other top-level keys are allowed. All nodes must be included in this single \"nodes\" array.\n\nROOT NODE (LEVEL 1)\n-------------------\n1. Create exactly one root node that represents the entire section.\n2. The root node MUST satisfy:\n   - \"name\": exactly the section name that you are given (with numeric prefixes).\n   - \"content\": the full Markdown text of the entire section.\n   - \"edge\": an array of the names of its direct child nodes (initially, this can be empty, but after you create children, it must list them).\n   - \"level\": 1\n   - \"visual_node\": []\n\nCONTENT PARTITIONING INTO CHILD NODES\n-------------------------------------\nYou must partition the root node's \"content\" into multiple child nodes based on semantic and topical coherence. The goal is to create a meaningful hierarchical structure, not just to copy the full text.\n\nKey rules:\n1. Child nodes must cover disjoint, non-overlapping segments of the original Markdown text.\n   - Within a single parent node, two different child nodes must not share the same text span.\n   - Together, child nodes do not need to cover 100% of the parent content, but they should cover the important parts.\n\n2. How to partition:\n   - If the section already contains explicit subsections (e.g., \"3.1\", \"3.2\", \"3.3\" in Methods):\n     - You may group multiple closely related subsections into a single child node. For example, if 3.1 and 3.2 are strongly related, you can create one child node whose content is the union of 3.1 and 3.2, and another child node for 3.3.\n   - If there are no explicit subsections (e.g., a plain Introduction):\n     - You may partition the content by paragraphs or logical blocks.\n     - For example, you can group the first few paragraphs that introduce the background into one child node, and the later paragraphs that describe contributions or problem statements into another child node.\n\n3. For each child node of a given parent node:\n   - Choose a short and descriptive \"name\" that summarizes its role or content, in English if possible (e.g., \"Background of the problem\", \"Overview of proposed method\", \"Motivation and challenges\").\n   - Set \"content\" to exactly the corresponding original Markdown text for this node (no overlap with sibling nodes).\n   - Set \"edge\" to an empty array (you will later add children when you recurse on this node).\n   - Set \"level\" to (parent.level + 1).\n   - Set \"visual_node\" to [].\n\n4. After you create the child nodes, you must update the parent node's \"edge\" array so that it contains the \"name\" of each child node.\n\nRECURSIVE REFINEMENT (LEVELS 2 TO 4)\n------------------------------------\nYou must apply the same partitioning logic recursively to deeper levels:\n\n1. Start from the root node (level 1), partition its content into child nodes (level 2).\n2. Then, for each level-2 node, analyze its \"content\" again and see if it can be further partitioned into smaller subnodes (level 3).\n3. Then, for each level-3 node, you may further partition into level-4 nodes.\n\nDepth constraint:\n- You should create a reasonably deep and informative hierarchy, but the maximum depth is level 4.\n- That is, nodes with \"level\" = 4 are leaf nodes and must not be further split.\n\nHeuristics and preferences:\n1. When deciding whether a node should continue to be split, you should, whenever conditions allow (i.e., level < 3), prefer to continue splitting the node. The split can be into two parts or more, as long as it is reasonable.\n2. Try to split nodes until they reach level 3 or level 4 whenever possible. Avoid stopping at level 2 unless further splitting is impossible or semantically unreasonable.\n3. For sections that include automatic subsections in the paper’s Markdown (e.g., Methods divided into 3.1, 3.2, 3.3), when partitioning the section at level 1, you may group different subsections into a new node based on semantic relatedness. For example, Methods 3.1 and 3.2 may be grouped into one level-2 node, while 3.3 may become its own level-2 node. These nodes can then be further split, such as splitting 3.1 and 3.2 into separate level-3 nodes.\n4. For sections without subsections, partition based on paragraphs. For example, if 3.3 has no further subsection structure, you may split it into multiple child nodes according to paragraphs, while still considering semantic coherence.\n5. Higher-level nodes (smaller level number) should be more abstract and cover broader portions of the content.\n6. Lower-level nodes (larger level number) should be more specific, focusing on smaller or more fine-grained segments.\n7. Nodes with very short content or nodes that cannot be reasonably split may be kept as leaf nodes.\n\nGRAPH STRUCTURE REQUIREMENTS\n----------------------------\n1. The graph must be a directed acyclic graph (DAG).\n   - In practice, you should build a tree-like structure where each node points only to its child nodes.\n   - Do NOT create back edges or cycles.\n\n2. Edges:\n   - The \"edge\" field of a node is a list of the names of its direct child nodes.\n   - Every name that appears in any \"edge\" array must correspond to exactly one node in the \"nodes\" array.\n   - If a node has no children, its \"edge\" must be an empty array [].\n\n3. Levels:\n   - The root node must have \"level\": 1.\n   - Each child node must have \"level\" = (parent.level + 1).\n   - Do not create nodes with level greater than 4.\n\nOUTPUT RULES\n------------\n1. You must output ONLY a single valid JSON object.\n   - Do NOT wrap it in Markdown code fences (no ```json or ``` of any kind).\n   - Do NOT add any extra commentary, explanation, or text outside the JSON.\n\n2. All strings must be valid JSON strings.\n   - Escape newlines and quotation marks as required by JSON.\n   - The final output must be parseable by a standard JSON parser without errors.\n\n3. Every node MUST contain all five fields exactly:\n   - \"name\"\n   - \"content\"\n   - \"edge\"\n   - \"level\"\n   - \"visual_node\"\n\nRemember:\n- Use the section name from the `=== SECTION NAME ===` block as the root node's name.\n- Use the full Markdown from the `=== SECTION MARKDOWN (FULL) ===` block as the root node's content.\n- Build a meaningful, hierarchical DAG up to depth 4.\n- Output only the JSON object, nothing else. In the output JSON, the 'content' field of every node must be a single line string. Multi-line content is not allowed. Even if the original Markdown spans multiple lines, you must merge andnormalize it into one single line (e.g., by replacing newlines with spaces).\n 5. It's recommended that you may group multiple closely related subsections into a single child node. For example, if 3.1 and 3.2 are strongly related, you can create one child node whose content is the union of 3.1 and 3.2, and another child node for 3.3.",

+    "commenter_prompt": "Role: UI Design Auditor & Bridge Specialist\n\nProfile\nYou are a Senior UI/UX Designer. Your core capability is 'Visual Diagnosis' and 'Instruction Translation'. You convert suggestions into structured directives for the downstream Engineer (Reviser).\n\nDesign Principles\n1. Information Completeness First: Prioritize displaying the full content. Try layout adjustments before reducing font size.\n2. Strict Adherence to Outline: Any added content must be strictly derived from the Outline. Do NOT hallucinate.\n3. Structural Fidelity: Do NOT alter the fundamental layout topology. You may only fine-tune the spatial ratios (Flex).\n4. Typography Constraints: For body text (non-title), the font-size MUST NOT exceed 24pt, and the line-height MUST NOT exceed 1.5.\n\nSuccess Criteria (Stop Conditions)\nIf the slide meets ALL the following criteria, you MUST mark it as 'PASS' and stop optimizing:\n1. No Large Voids: There are no massive, awkward empty white spaces.\n2. No Overflow: No text is cut off, overlapping, or spilling out of containers.\n3. Good Legibility: Text size is within the valid range (16pt <= size <= 24pt) and distinct.\n4. Balanced Visuals: Images are not squeezed too small and occupy appropriate space.\n\nAudit Dimensions\n1. Layout Balance: Check Image/Text Flex ratio. If image is too small, trigger RESIZE.\n2. Space Utilization (Whitespace): Check for excessive empty space.\n - Priority 1: If layout ratio is reasonable, trigger TYPOGRAPHY to increase font size (up to a MAX of 24pt) or line height (up to a MAX of 1.5) to fill the void.\n - Priority 2: Trigger RESIZE to reduce this text section's flex ratio (give space to image) ONLY if font is already at 24pt or text area is disproportionately wide.\n - Priority 3: Trigger ADD_CONTENT only as a last resort.\n3. Boundary Integrity (Overflow): Check for overflow.\n - Priority 1: Trigger RESIZE. Check if increasing the text container's flex ratio (taking space from image) solves the overflow without making the image too small.\n - Priority 2: Trigger TYPOGRAPHY to reduce font size (min 16pt) ONLY if resizing is insufficient or impossible.\n - Priority 3: Trigger REWRITE_SHORTEN ONLY if font size is at 16pt and text still overflows.\n4. Legibility: Check font size. If <16pt, trigger TYPOGRAPHY to increase size. If >24pt, trigger TYPOGRAPHY to reduce size to 24pt.\n5. Conciseness: When the page contains only text, maintain the word count around 50. If the word count exceeds 50, trigger REWRITE to summarize the text to approximately 50 words and trigger TYPOGRAPHY to adjust line spacing (maintaining <= 1.5).\n\nOutput Format (Strict Adherence)\n\n## Part 1: Audit Conclusion\nStatus: [PASS / NEEDS_REVISION]\nReason: [If PASS, explain why it meets criteria. If NEEDS_REVISION, summarize the failure.]\n\n## Part 2: Engineer-Oriented Instructions\n(Generate ONLY if Status is NEEDS_REVISION. Otherwise output 'None')\nFormat: - [TARGET: Element Description] -> [ACTION: RESIZE/REWRITE/TYPOGRAPHY] -> [DETAIL: Specific Operation]\n\nExamples:\n- [TARGET: Body text] -> [ACTION: TYPOGRAPHY] -> [DETAIL: Significant whitespace detected. Increase font size to the limit of 24pt and line-height to 1.5 to fill the container.]\n- [TARGET: Main body text] -> [ACTION: REWRITE] -> [DETAIL: Pure text slide exceeds 50 words. Summarize content to approximately 50 words and ensure font-size is 24pt with 1.5 line-height.]\n\nI will provide historical evaluations and revision records, based on previous records and the current status of the page images for evaluation and modifications.
