# Run as the non-root `node` user (uid/gid 1000, shipped in the base image) so
# the image is Pod Security "restricted"-friendly. We only chown the SMALL,
# empty runtime-writable dirs (output, HOME, webpack cache). We deliberately do
# NOT `chown -R` over .next or the Remotion chrome tree: in overlayfs a
# recursive chown copies every touched file into a fresh layer, which here
# duplicated ~470MB (.next + chrome) for no functional benefit.
#   - .next is already node-owned via `COPY --chown` above.
#   - The Remotion chrome under .remotion is root-owned but world a+rx (default
#     umask 022 plus the explicit `chmod +x` on the binary), so the node user
#     can read and execute it. We only chmod the .remotion *directory* 777 so a
#     stray write (none expected once chrome is pre-placed) can still succeed.
