docs: update the reference topology diagram to the latest export - #1200

Conversation
Swaps in the new export, which adds the diagram title and a key marking the tool calling hot path and the arcade deploy path. The file is JPEG data despite the .png name it arrived with, so it lands as .jpg rather than lying about its format. Re-encoding it to real PNG was the other option, but that doubles the file to 3.8MB and recovers no detail, since the JPEG artifacts are already baked in. Intrinsic dimensions go to 7800x4280. Same aspect ratio as before, so the layout is unchanged. The alt text picks up the application and worker plane split and the key. ~ 🎹 Evanescence, Evan's Agent

Follow-up to #1194, which merged with the previous export. This swaps in the newer diagram.
What changed
The new export adds the diagram title and a key marking the tool calling hot path and the
arcade deploypath, and draws a clearer split between the application plane and worker plane clusters.On the file extension
The export arrived named
.pngbut is actually JPEG data (filereportsJPEG image data, JFIF standard 1.01), so it lands here as.jpgrather than carrying an extension that lies about its format.Re-encoding to a real PNG was the alternative, but it doubles the file to 3.8 MB and recovers no detail — the JPEG artifacts are already baked into what Whimsical exported. A genuinely lossless PNG would need a fresh export from the source diagram, not a conversion of this one.
Layout
Aspect ratio is identical (1.8224), so nothing shifts. Verified in a browser at a 1440px viewport — the figure measures 832px, exactly matching the body paragraph and the services table, and the dark-mode dimming from #1194 still meets the panel seamlessly.
width/heightare updated to the new intrinsics so there is no layout shift, and the alt text picks up the plane split and the key.~ 🎹 Evanescence, Evan's Agent
Note
Low Risk
Documentation-only image and alt-text update with no runtime or security impact.
Overview
Replaces the platform architecture reference topology figure with a newer Whimsical export on the deploy architecture page.
The linked asset moves from PNG to
.jpg(matching the actual JPEG export) andwidth/heightare set to 7800×4280 so layout stays stable. Alt text is expanded to match the updated diagram: separate application plane and worker plane clusters, additional in-cluster services (Usage, embedding/search, OpenFGA, custom MCP servers), egress to container registries, and a key for the tool-calling hot path andarcade deploypath.Reviewed by Cursor Bugbot for commit 79fd379.
