-#  PINNING RULES FOR HF SPACES
-#  ────────────────────────────
-#  1. NEVER pin gradio — HF force-installs gradio==6.x in [base 6/7].
-#     Any pin causes a ResolutionImpossible error → exit code 1.
-#
-#  2. NEVER hard-pin torch/torchvision to a specific patch version.
-#     The HF base image ships a pre-built torch; an exact pin that doesn't
-#     match the available wheel causes "No matching distribution found".
-#     Use a floor (>=) so pip can pick the pre-installed wheel.
-#
-#  3. NEVER pin timm to 0.9.x — timm 1.x removed the direct
-#     timm.models.efficientnet.tf_efficientnet_b7_ns import path.
-#     Our app.py already has a try/except fallback, but a hard pin
-#     to 0.9.x will conflict with timm 1.x that Gradio 6 may pull in.
-#     Use a floor instead; the fallback import handles both versions.
-#
-#  4. numpy: Gradio 6 requires numpy>=1.0,<3.0. numpy 1.26.x is fine but
-#     do not hard-pin it — let pip choose within that window.
+#  HF Spaces runs Python 3.13. Rules:
+#  1. Never pin gradio — HF force-installs gradio==6.x in [base 6/7].
+#  2. Use floor-only constraints so pip picks available cp313 wheels.
+#  3. numpy ≥ 2.0 — first release with a cp313 wheel (1.26.x source-builds
+#     and fails on Python 3.13).
