Puter.js + Claude

Started over. Chat-first. Smaller surface. Better operator flow.

The old Claude page was overbuilt. This version is a fresh implementation centered on the only things that matter: model selection, system context, attachment ingestion, deterministic request preview, and a usable transcript.

Live browser execution against puter.ai.chat() with streaming or buffered responses.
Attachment ingestion for text, markdown, JSON, JavaScript, TypeScript, HTML, CSS, Solidity, and log files.
Inspectable prompt assembly so the actual request envelope is visible before execution.
