# Apt only provides system-level deps; Python deps (textual, python-mpv,

  # 1) Self-contained venv inside the staged package.
  python3 -m venv "${stagedir}"

  # 2) Install the app + its PyPI deps. Calling pip as `python -m pip`
  #    (instead of the `pip` script) avoids the kernel's shebang length
  #    limit, which the long ${pkgdir} staging path can exceed.
  #    --no-compile: bytecode is generated in step 4 with clean paths.
  "${stagedir}/bin/python" -m pip install --no-cache-dir --no-compile .

  # 3) Strip the staging prefix from every *text* file that embeds it:
  #    console-script shebangs, activate scripts, pyvenv.cfg (its
  #    "command =" line records ${pkgdir} on Python 3.11+), and pip's
  #    RECORD/direct_url.json metadata. --binary-files=without-match
  #    guarantees sed never touches a binary file.
  grep -rlZ --binary-files=without-match "${pkgdir}" "${stagedir}" \
    | xargs -0r sed -i "s|${pkgdir}||g"

  # 4) Pre-compile bytecode with the staging prefix stripped (-s), so
  #    .pyc files and tracebacks reference /opt/... — and Python never
  #    needs to write into the root-owned /opt at runtime.

  #    never ${pkgdir} — pkgdir is a temporary staging root that is
  #    deleted after the .deb is built.
