Demonstrates the WorldEnvironment post-process Properties that now drive the
desktop Vulkan renderer with the same results as the web backend:

  - SSAO with tunable radius / bias / intensity (dedicated compute pass).
  - Tonemap operator selection (ACES / Neutral / Reinhard / Uchimura) plus
    white-point, matching the web WGSL enumeration.
  - FXAA toggle.
  - Depth-of-field driven by the canonical ``dof_max_coc`` (resolution-aware).

Controls:
    A / D       - Orbit camera left / right
    W / S       - Pitch camera up / down
    Q / E       - Zoom in / out
    1           - Toggle SSAO
    2           - Cycle tonemap operator
    3           - Toggle FXAA
    4           - Toggle depth of field
    Up / Down   - SSAO radius +/-
    Left / Right- SSAO intensity -/+
    Escape      - Quit
