Participant notes

“The Semantic Foundations course forced us to rewrite our dashboard shell. The week-two diff review on our sidebar landmark map caught three nested nav issues before QA opened tickets.”

“Landmark module was dense; still worth it because we now ship a heading contract with every release train.”

Questions with honest limits

We stay inside web markup. Document remediation is out of scope, though we can suggest partners who specialize in tagged PDFs.
