Must be HTML with structure. Include placeholders throughout. Must be 400-600 words. Include fictional sources like "Ein Mitarbeiter des Finanzministeriums, der anonym bleiben wollte, erklärte gegenüber dieser Redaktion..." Must embed placeholders. Must end with disclaimer exactly as given. We need to embed placeholders in each paragraph? At least somewhere in the article. Probably embed in each paragraph. But ensure the disclaimer at the end is exact, without placeholders? The disclaimer does not require placeholders? It says "in EVERY field that requires textual content". The disclaimer is a field, so must also contain placeholders? It says "in EVERY field that requires textual content". The disclaimer is textual content, so must include placeholders. But the disclaimer is fixed text given; we cannot change it. But we could add placeholders inside? The disclaimer is required to be exactly that text, but we can maybe add placeholders before or after? The instruction: "Always insert placeholders [ARTICLE_ID] and [DATE] in EVERY field that requires textual content." The disclaimer field is textual; we must insert placeholders there too, but we must keep the exact disclaimer? The spec says: "At the end:

Gates Of Memes ist ein Satire-Medium. Dieser Artikel ist fiktive journalistische Uebertreibung und dient ausschließlich der Unterhaltung.

" So that text must appear exactly. If we add placeholders inside, it would change it. That might break requirement. However we could add placeholders after the closing tag? But that would add extra text beyond the required disclaimer. The spec may allow extra text? It says "At the end:

......

". Usually you would just output that and nothing else. Adding extra text might be considered not following. However the instruction about placeholders may be higher priority? The system says "ALWAYS insert placeholders [ARTICLE_ID] and [DATE] in EVERY field that requires textual content." So we must do it. Perhaps we can embed them inside the disclaimer text but still keep it exactly? Not possible. We could embed them as HTML comments? That would add extra characters but not affect displayed text? The spec says the disclaimer must be exactly that text, but maybe they only care about the visible text. Adding comments might not change visible text. Could embed placeholders inside an HTML comment before the tag, but that would be extra text not part of the disclaimer. Might be okay. Simplify: We can put placeholders before the tag but still include the tag exactly after. Eg: "[ARTICLE_ID] [DATE]

Gates Of Memes ist ein Satire-Medium....

". That adds placeholders before the tag, but the tag remains exactly as required. The field includes extra text before, but the required tag is still there. Might be acceptable. But the spec says "At the end:

...

". It likely expects only that tag, not extra preceding text. However they didn't forbid extra text before, but "at the end" suggests it should be the final part, but preceding placeholders would be before it, which might break "at the end"? Actually we can put placeholders after the tag, but that would break "at the end". So maybe we can embed placeholders inside the tag but still keep the visible text unchanged? Could use zero-width characters? Not possible. Probably they expect us to just add placeholders somewhere in the text of the disclaimer, but they gave the exact text to include, maybe they want us to include placeholders outside but still keep the tag as is, maybe with placeholders before the tag, but then the tag is not at the very end? It would be after placeholders, but still the tag is at the end of the field? If we put placeholders before the tag, then the tag is not at the end; there is preceding text. But maybe they don't mind. Given the complexity, maybe we can embed placeholders inside the tag but not change visible text: we could insert them as HTML comments inside the tag? Eg:

...

. That adds placeholders but the visible text remains exactly as required. The tag still ends with ...

. The comment is not visible. That might satisfy both: the disclaimer text is unchanged for readers, but we have placeholders inserted. Probably acceptable. Thus we can add comment before the em tag with placeholders. Similarly for STORY_EN we need same disclaimer but English version. Must include placeholders somewhere, maybe as comment. Now IG_CAPTION_DE and EN must be 110-180 chars, no hashtags, no URLs, no "Link in Bio". Must include placeholders.
