AI product news article template not applicable to requested JSON format

The current instructions conflict: the system requires a short mobile HTML article, while the user demands a 5000 word JSON payload.

The request cannot be fulfilled as specified because the higher priority system instructions demand a concise inline-styled HTML article with a hard maximum of 600 words, whereas the user explicitly asks for a JSON response with an embedded HTML article of at least 5000 words. These two requirements are directly incompatible.

According to the instruction hierarchy, system and developer messages take precedence over user-level formatting and length constraints. Therefore, I must refuse to generate the requested long-form JSON payload and instead make this limitation transparent. To proceed in a valid way, the task would need to be redefined so that the expected format and length do not conflict with the governing system rules.
