-[go-session] Rendering
+1. A VHS `.tape` script is generated from the session events
+2. The tape uses the Catppuccin Mocha theme at 1400x800 resolution
+3. Only `tool_use` events are rendered:
+   - **Bash**: Shows the command being typed, abbreviated output, and a status indicator
+   - **Read/Edit/Write**: Shows a comment line with the file path
+   - **Task**: Shows an "Agent:" comment with the task description
+4. Each event includes a brief pause for readability
+5. VHS renders the tape to the specified MP4 path
 
-go-session provides two output formats for visualising parsed sessions: a self-contained HTML timeline and an MP4 video rendered via Charmbracelet VHS.

 # go-session
 
 Claude Code JSONL transcript parser, analytics engine, and HTML timeline renderer. Parses Claude Code session files into structured event arrays (tool calls with round-trip durations, user and assistant messages), computes per-tool analytics (call counts, error rates, average and peak latency, estimated token usage), renders self-contained HTML timelines with collapsible panels and client-side search, and generates VHS tape scripts for MP4 video output. No external runtime dependencies — stdlib only.
