Need HTML structure with

. Actually they said: HTML:

. Aufbaum: Lede-Absatz ->

Hintergrund

->

Reaktionen aus dem In- und Ausland

->

Ausblick

. Likely they want to embed headings inside paragraphs? They said use tags:

. Possibly they want to start with

??? Let's parse: "HTML:

." Means the first tag is

. That seems odd. Perhaps they want the Lede paragraph to start with

??? Actually typical HTML:

... but they wrote

. That seems they want to open a

then an

then . Might be mis-specified. But we can follow: We'll produce something like:

Jesse Pollak zieht sich nach Fehlkalkulation beim Social‑Crypto‑Ansatz aus Base‑Leitung zurück

But they said Lede paragraph first, then

Hintergrund

etc. So maybe they want:

Der Mitbegründer ...

Hintergrund

... But they explicitly said HTML:

. That seems ambiguous. Let's just produce a simple HTML that respects structure but includes those tags. We can do:

Jesse Pollak zieht sich nach Fehlkalkulation beim Social‑Crypto‑Ansatz aus Base‑Leitung zurück

But that's mixing tags incorrectly (h2 inside p). Better to keep proper structure:

maybe not allowed but they asked that way. However they want the lede paragraph, then headings. So maybe they want:

Lede Text...

But that seems weird. Maybe they intend: The first paragraph should be wrapped in

... and then close tags? Actually they wrote: "HTML:

." Possibly they want the headings to be opened inside a paragraph? Hard. Simplify: We'll output the article in plain text with HTML tags as described: start with

(then the title?), then later

... but that duplicates. Might be okay. Better to follow literal: Use

at beginning of article, then close tags at appropriate places? But they want hierarchical structure: lede paragraph ->

Hintergrund

->

Reaktionen aus dem In- und Ausland

->

. So maybe they want the article to start with a paragraph that contains the lede, then headings. The initial tag they gave could be just a placeholder for the start of HTML. Let's produce:

Jesse Pollak zieht sich nach Fehlkalkulation beim Social‑Crypto‑Ansatz aus Base‑Leitung zurück

Hintergrund

...

Reaktionen aus dem In- und Ausland

...

Ausblick

...

...

That includes

tags, and also a

for lede. No

at beginning? But they said HTML:

. Might be they want to start with that specific sequence:

. Let's include that exactly at start of document. So first line:

Jesse Pollak ...

Then later we need

Hintergrund

etc. That would create nested h2 inside h2? Might be okay. Let's do:
