modern conference stage 3d model

Create a realistic modern conference stage for a public speaking simulator. The stage should be medium sized, slightly elevated (about 1 meter), with a matte black floor and clean professional design. Add a staircase only on the front-right side of the stage. Place a modern black podium with a mounted microphone on the front-left side of the stage, slightly toward the front edge. Behind the stage add a large dark backdrop wall with glowing text that clearly says “OUTERVIEWER” in all capital letters. From the top of this back wall extend a solid roof structure forward above the stage. Mount professional stage lighting rigs on this roof pointing toward the podium area with soft white spotlights. The stage should look like a real tech conference presentation environment. No audience, chairs, or people. Fully modeled realistic 3D asset, game-ready, clean geometry, no grayboxing.
