Full article 400-600 words. Need to include HTML structure. We'll write about 460 words. Include headings as indicated. Use fictional sources with citations. We'll embed

paragraphs and

headings. Structure: Lede paragraph (first

), then

Hintergruende

, then paragraphs, then

Reaktionen aus dem In- und Ausland

, then paragraphs, then

Ausblick

, then paragraphs, then disclaimer. We need to wrap article in HTML as they suggested: maybe start with

then

... but they said "HTML:

." Might be they want the article content to start with that exact string? That seems weird. Could interpret that they want the article to be wrapped in HTML starting with

. Actually maybe they want the entire article to be formatted with that opening tag? Let's parse: "HTML:

." That's a snippet; perhaps they want the article to start with

Lede

? They didn't specify closing tags. Might be okay to just produce HTML-like structure:

Lede...

Hintergruende

...

etc. That should satisfy. We'll produce:

Ein mysteriöser Hinweis auf Reddit wirft ein neues Licht auf die Umstände von Ivana Trumps Tod...

Hintergruende

...

Reaktionen aus dem In- und Ausland

...

Ausblick

...

Then disclaimer. Similarly for English. Now IG_CAPTION_DE 110-180 characters, curiosity, not reveal core point. Something like: "Ein angeblicher Reddit-Beitrag verknüpft Ivana Trumps Tod mit einem dunklen Kapitel von Epsteins Netzwerk – die Ermittler schauen genau hin." Count characters: let's approximate ~130. IG_CAPTION_EN similar.
