Orientation is a property of the composition, not a user choice — the backend's portrait/landscape presets are tied to the comp's authored aspect ratio. Letting users pick "1080p portrait" for a landscape composition just produces a wrong-aspect render. The dropdown now exposes three scale choices (Auto / 1080p / 4K) and maps to the correct portrait/landscape preset based on the active composition's data-width / data-height. Native <select title> tooltips are unreliable across browsers, so the resolved dimensions render inline in each option label (e.g. "1080p · 1920×1080") — always visible, no hover needed. App.tsx tracks the active comp's dimensions by listening for the existing hf-preview state/timeline postMessages (same source the caption-detection logic uses) and passes them to RenderQueue. The useRenderQueue / backend contract is unchanged: RenderQueue still emits "landscape" | "portrait" | "landscape-4k" | "portrait-4k" | "auto".
