Parked: Browser and WebGPU

The browser playground and WebGPU path are successful completed assets. They are parked for active factory work.

Do not spend near-term time on:

• Astro migration
• landing page polish
• HN/launch prep
• additional WebGPU optimization
• browser-first model gallery expansion

Reopen only if the factory proof needs a public readout, demo, or artifact viewer that cannot be served by the CLI/report path.
