Colophon

• Angular 22.2.0, using standalone components, signals, and zoneless change detection.
• Static prerendering with @angular/ssr. Every page is plain HTML at build time, and there is no server at runtime.
• RxJS drives the simulation on the home page, bridged to signals with toSignal.
• The simulations and the live chart are drawn by hand on a canvas, with no chart library.
• The live chart is a Web Component built with Angular Elements. The case study loads it the way any other site would, and a plain HTML sandbox page proves it needs no framework around it.
• Page changes use the browser’s View Transitions API through the Angular router. Motion animates steps inside two demos and is only downloaded with them.
• The SciChart panel loads SciChart’s free community edition from jsDelivr only when you press its button. That edition shows a watermark and sends SciChart anonymous usage data, including the page address.
• Tailwind CSS v4, with colours and type sizes defined as CSS custom properties.
• Fira Code for everything, self-hosted and limited to the Latin character set (36 KB). Icons are Tabler icons through ng-icons, and only the ones used are bundled.

• Pages work without JavaScript. Only interactive demos need it, and each has a static fallback.
• Every demo is downloaded only when it scrolls into view, so the home page stays small.
• Animation stops when your system asks for reduced motion, and the simulation pauses when the tab is hidden.
• Unit tests run on Vitest. End-to-end, accessibility (axe) and screenshot comparison tests run on Playwright, on desktop and mobile, in light and dark.
• Every push runs the same checks in GitHub Actions: formatting, the tests above, Lighthouse with every category at 95 or above, a JavaScript budget for the home page, and a check of every link. Any failure fails the build.

• The colours come from control-room consoles: a cool grey-blue ground, teal for messages in flight, amber for work done, and red only for failures.
• The page layout borrows its lanes from queue diagrams. Section headings sit in a narrow lane and content in a wide one.

Real numbers from the last measured build, not claims. The script that produces them is in the repository, and CI runs it on every push.
