   NEXXORE — Workspace Shell (Phase 1: Terminal + Swarm)
   Shared top strip so /terminal and /swarm read as one workspace.
   No include mechanism exists in this codebase — the matching
   <div class="nx-shell-nav">...</div> markup is duplicated in
   each page's <body>. Keep both copies in sync when editing.
