Provide HTML. We'll write maybe about 470 words. Structure: start with lede paragraph wrapped in

... maybe they want the lede as heading? I'll produce:

Ein verheerender Waldbrand in Andalusien hat in den letzten Tagen mindestens zwölf Menschenleben gekostet.

Then

Hintergrund

etc. But they said "Aufbau: Lede-Absatz ->

Hintergruende

->

Reaktionen aus dem In- und Ausland

->

Ausblick

". So maybe they want just the lede as a paragraph (no heading) then headings for the sections. Thus maybe we start with

... lede ...

then

Hintergrund

then paragraph etc. But they also said "HTML:

." That seems contradictory. I'll just produce:

Hintergrund

... That's not lede. Hmm. Better: They gave example of opening tag:

. Possibly they want the entire article to start with that pattern for each heading? Actually they might want each heading to be wrapped like that. But they also said structure includes headings already. I'll produce article like:

Lede paragraph ...

Hintergrund

...
