Hero depth passes (inputs-v1)

Depth passes for the TimeFlight hero (Mexico City historic centre → Tenochtitlan, 1519), so the GPU stage can run without Blender.

polish2_inputs.zip (212 MB, sha256 0a6a81f7b7e4b5aff3042b146caa625d8e8f2ae4a93be55086fc02e72a1dfcc6), rendered headless with blender/render_place.py along the real camera path:

Folder	Use
present_r1024_361, 1519_r1024_361	the hero: 1024×576, 361 frames (15 s), present day and 1519
present_r576x320_121, 1519_r576x320_121	the 5 s test: 576×320, 121 frames

Each folder holds 16-bit depth PNGs, the inverse-depth control video for the LTX guide, Blender colour and edge passes, and render.json (camera per frame, origin, depth scale).

Use it: open colab/timeflight.ipynb (it downloads this zip by default), or on your own machine unzip it and run bash colab/flight.sh <folder> hero_s2. See the README.
