# any host running this image). Idempotent.
#
# DELIBERATE: not `set -e`. Weight download and Blender health-check are
# best-effort; the orchestrator must start even if either fails. /v1/health
# and /v1/tasks work without weights or Blender; inference / rig / GLB
# routes will surface clear errors at request time if their deps are
# missing. Better than dying silently in a Space we can't easily debug.
