CEF in-world browser

Summary

Chromium Embedded Framework integration for rendering web content onto arbitrary 3D surfaces. Browser instances are managed as world-surface textures that can be mapped to any mesh/material.

Motivation

Spatial computing benefits from in-world web content — reference documentation, live dashboards, web apps rendered on 3D surfaces. Rather than a flat overlay, web content should be a first-class world object.

Design

• CEF integration: Linux-only; CMake manages CEF download/version pinning
• Surface API: app.engine.browser:create-surface with id, url, texture-name, width, height, max-fps
• Texture binding: :texture-name binds the rendered page to any mesh/material texture slot
• Input routing: send-mouse-move, send-mouse-click, send-mouse-wheel, set-focus for world-space interaction
• Opt-in cube demo: 6-face browser cube via SPACE_BROWSER_CUBE_DEMO=1

Tasks

• [x] CEF library download and CMake integration
• [x] Browser surface creation and GL texture output
• [x] Mouse/keyboard input routing
• [x] Multi-surface support
• [x] Opt-in cube demo
