Speed
On a slow mobile connection the home page renders in under one second (internal audit, 23 October 2026). Pages are pre-built and compressed, images use the modern AVIF and WebP formats, and the heading font is 17 kB.
Under the hood
How this website is built
A software supplier's website is a good place to check how it works. These figures are calculated with every build of the site, not by hand.

Privacy
No cookies, no visitor analytics, no fonts, scripts or maps from third-party servers. The contact form goes to our own server.
Security
Strict security headers — the page may not run any inline script or style (Content-Security-Policy without “unsafe-inline”), cannot be embedded in another site and works only over HTTPS (HSTS preload).
Accessibility
We check against WCAG 2.2 at level AA; primary buttons have AAA-level contrast. The site can be used with a keyboard and respects reduced motion and the system's dark or light theme.
Technology
Static pages built with Astro, our own CSS without libraries and a little of our own JavaScript. It runs on our server via nginx with HTTP/2 and TLS 1.3. Before publishing, every change passes an automated gate (links, translations in eight languages, page size), and we test accessibility in three browser engines.
