Now the article body.
Start directly with YAML. No extra text.

Wait, the prompt says: "SPEICHERE unter: data/pipeline/blog/2026-07-15_3-horizons_luft-_hamburg.md" - this is just a meta instruction, but I should not output that as text, just write the article. "Antworte NUR mit dem fertigen Artikel. Keine Gedankenschritte... Starte direkt mit dem YAML-Frontmatter (---)."

Let's integrate the provided data:
- BIP DE Q1 2026: +0,3 %
- Großhandelspreise Mai 2026 (Vj.): +5,9 %
- EZB-Leitzins Juni 2026: 2,5 % (from rail part)
- Tariflohnentwicklung 2026: +2,6 % (from rail part)
- Exportquote Yachten: ~70 %
- Beschäftigte C30.12: 5-6.5k, C30.2: 28-35k
- Deutschlandtakt-Programm
- Mega-Yachten >40m Weltmarktführer

Apply to Hamburg:
Hamburg is home to Airbus (Finkenwerder - final assembly A320, A350 fuselage), Blohm+Voss (Thyssenkrupp Marine Systems - naval, yachts, repair), and a strong maritime supplier network. Rail: Siemens Mobility has a Hamburg office/traction, but mostly Hamburg is a maintenance hub. I will focus on Shipbuilding (C30.12 / C30.1) and Aerospace (C30.3) and Rail (C30.2) as per "Luft-/Raumfahrt / Schiffbau (WZ C30)".

Horizon 1 (Core):
Defend the core. Mega-Yacht outfitting, Airbus supply chain. Material costs +5.9% (GFK, Carbon, Alu). Need to pass on costs, optimize working capital (EZB 2.5% makes financing expensive). Use of digital procurement.

Horizon 2 (Emerging):
Green transition. Hydrogen propulsion for yachts/workboats. MRO (Maintenance, Repair, Overhaul) for the 70% export fleet coming back for refits. Digital Twins for ship lifecycle.

Horizon 3 (Future):
Autonomous shipping (Hamburg is testing autonomous vessels in the port). Urban Air Mobility (Airbus involvement). Circular composites recycling (GFK waste is a huge issue).
