Restructure the Features Overview into the same six groups the docs
sidebar uses (Stacks & Deployments, Observability, Fleet & Multi-Node,
Security & Identity, Automation, Platform) plus a short Reference tail.
Add catalog entries for 17 shipped features that the previous overview
never mentioned: Stack Activity, Stack File Explorer, Deploy Progress,
Deploy Enforcement, Blueprints, Git Sources, Global Search, Pilot Agent,
Sencho Mesh, Fleet Federation, Fleet Actions, Fleet Sync, Fleet Secrets,
Two-Factor Authentication, CVE Suppressions, Auto-Heal Policies, Stack
Sidebar.
Fix two factual inaccuracies:
- Fleet View blurb wrongly gated search, sort, filter, and stack
drill-down behind Skipper. The deep-dive is explicit that those are
available on every tier; only the bulk Update All action inside the
Node Updates modal is paid.
- Auto-update entry was titled and described as a scheduling system.
The deep-dive page is the Auto-Update Readiness board (risk tags,
changelog previews, rollback targets); the scheduler lives under
Scheduled Operations.
Add three hero screenshots captured from production at 1920x900,
illustrating the redesigned cockpit visual language: Home dashboard,
stack anatomy, and fleet topology.
