Navigation (v2_optimizer._sync_enterprise_navigation + v2-mkdocs.yml):
- "Topic Map" becomes a collapsible hub holding the three orientation
pages — Topic Map (section index), Methodology, Technical Tags — since
they are all about how the portal is structured.
- "Agentic Video Hub" is promoted above Intelligence Digest as a
prominent top-level dropdown, keeping its category subpages.
Video subpages (v2_video_portal):
- Drop the in-page "## Table of Contents" block; it duplicated Material's
native right-column "On this page" TOC (toc.follow), matching how the
topic pages already omit it. The technology ordering list is retained
internally to drive section render order.
