Summary by cubic

Replaces the cloud browser quickstart image with an ASCII flow diagram so the flow renders consistently in light/dark mode and in the LLM-generated docs.

• Removes the light/dark SVG image pair from docs/cloud/browser/quickstart.mdx.
• Adds the same ASCII flow diagram to docs/cloud/llms-full.txt and docs/llms-full.txt to keep generated LLM docs in sync.
• Verified at desktop and mobile viewport widths with no horizontal or code-block overflow.
