I fixed a number of the low-hanging a11y issues that you identified.
As for using modern web tooling, keep in mind there are many business and technical tradeoffs that go into any engineering decision. In this case, dynamically rendering the content makes it easier in the future to require aspiring hardware engineers to pass a test demonstrating knowledge of WCAG 2.0 standards before unlocking any educational hardware content.
It's much better now; thanks. Most of my remaining complaints are now obsolete or easily avoidable. I think the only remaining issue is the contrast on the Projects, Shop, About, FAQ, Support text, but your existing design might be pretty enough to justify that.
… Wait, those changes applied to all of the pages‽ I'm starting to finally see the appeal of those web frameworks.
