No cookies
No first- or third-party cookies are set. The site therefore needs no cookie banner.
This website is built by hand — no site builder, no theme, no content management system. For the technically curious, this page shows how it is structured, developed and published automatically.

Build instead of runtime platform
The site is built on Astro 6 and Node 22. Astro generates complete static pages at build time. Running it therefore requires no application server, no database and no additional web framework in the browser.
Design guidelines
Two agent skills supported design and quality assurance: frontend-design helps with a distinctive and consistent visual implementation; UI-UX-Pro-Max adds guidelines for user guidance, typography and accessibility.
Static delivery
Only finished pages and local resources are published. This reduces dependencies, operational effort and attack surface. Documents are always served fresh; unchanged images and fonts may stay in the browser cache for 30 days.
Small technical footprint
For its technical baseline the homepage needs around 22 KB compressed and 4.9 KB of its own JavaScript. No external scripts are loaded. The content stays accessible regardless of optional presentation features.
Presentation with clear limits
Dark mode can be toggled and otherwise follows the system setting; the choice is remembered locally in the browser. Motion is used sparingly and is reduced when the system requests it.
Responsive, local media
Images are provided in several sizes and in AVIF and WebP. The browser loads a variant suited to the device. Logos and graphics are used as scalable SVG files. All media and fonts are stored locally, which keeps data transfer and dependencies under control.
Privacy and security
The architecture works without cookies, tracking, form data and third-party services. A Content Security Policy limits permitted resources; HSTS enforces encrypted connections. Data minimisation is thus part of the technical foundation, not an afterthought.
Collaborators
This website was not built alone. Three AI tools were involved in concept, implementation, review and finishing. Direction, decisions and responsibility stayed human.
