# =============================================================================
# MMaxAI Hosting Panel — Docker image for HF Spaces.
#
# Build context = hosting_panel/ directory contents (uploaded directly,
# NOT the full repo).  All COPY paths are relative to that context root.
#
# Works for BOTH targets:
#   * HuggingFace Space:  HF expects port 7860 (Render too — uses $PORT,
#                        so we default to 7860 if $PORT is unset).
#   * Render Web Service: $PORT is set automatically by Render.
#
# Entry point: app:app (app.py exports the FastAPI instance).
# The sys.path self-patch at the top of app.py ensures bare imports
# (from config import ...) resolve regardless of CWD.
#
# Shell form (NOT JSON/exec form): some PaaS runners (Render included)
# pass the raw `CMD ["sh", "-c", "..."]` array to /bin/sh verbatim,
# which fails with `/bin/sh: 1: [sh,: not found`.  Shell form avoids
# this entirely.
