# Enhance TimelineCanvas Documentation for Knowledge Base

Apply Knowledge Base Enhancement Strategy to `apps/portal/view/news/tickets/TimelineCanvas.mjs`.

- **Class Summary:** Document its role as the "Coordinator" bridging the DOM/Store and the Canvas Worker.
- **Alignment Logic:** Add detailed intent-driven docs to `onTimelineDataLoad` explaining the "Overlay Alignment" strategy (fetching DOM rects of avatars/badges to align the canvas nodes perfectly).
- **Architecture:** Explain the interaction with `Portal.canvas.TicketCanvas` (the SharedWorker singleton).
