+- `requirements.txt` installs `depth_anything_3` directly from its GitHub
+  source rather than PyPI. Its PyPI availability has been inconsistent
+  (sometimes resolvable, sometimes not, depending on when/where you build) —
+  installing from the maintainers' repo directly sidesteps that entirely,
+  at the cost of a longer build (it compiles from source rather than pulling
+  a prebuilt wheel).
+- `python_version: "3.11"` is still pinned above. Even installing from
+  GitHub, the package's own metadata declares `Requires-Python: <=3.13,>=3.9`,
+  and a `3.13.x` patch release can fail that check due to how version
+  comparison works (`3.13.14` sorts after `3.13`) — keep this pin.
