OpenRouter trace viewer

Paste a raw OpenRouter network trace with `data:` lines. This viewer ignores blank lines and comment markers, reconstructs streamed text, stitches together tool-call deltas, and surfaces the final usage payload.

Input trace

Paste the raw log, including `: OPENROUTER PROCESSING`, `data: ...`, and `[DONE]` lines.
