Routes

• / renders the default document and its first entry. Documentation is the default only when it has visible concepts; otherwise an available project plan is used as the root document.
• /documentation/ renders the first visible documentation concept.
• /documentation/:conceptId/ renders a documentation concept.
• /project-plan/ renders the first project plan section.
• /project-plan/:sectionId/ renders a project plan section.
• /task-tree/ renders the fullscreen task graph workspace.
• /task-tree/:taskId/ renders the fullscreen task graph workspace with the selected task drawer open.
• Function and type entries use hash anchors under the owning documentation concept route.

Behavior

• The header navbar lists every recognized document in the collection.
• The sidebar shows documentation categories for documentation pages.
• The sidebar shows project plan areas for project plan pages.
• Task tree pages do not use a sidebar; the graph is the primary workspace.
• Search is scoped to the active document.
• Documentation search returns concepts, function entries, and type entries.
• Project plan search returns plan sections and searches section summaries, intro Markdown, and detail blocks.
• Project plan pages render section summaries, free-form intro Markdown, and ### detail blocks.
• Task tree search returns tasks.
• Task tree pages render a pannable, zoomable SVG graph with task statuses, decomposition edges, dependency edges, and a right-side detail drawer.
• Inline type references inside function and type cards link back to the owning TypeReferenceTarget.
