#   sharp-linux-x64-<version>.node   patched addon (imports vips_g_*, not g_*)
#   libvips-cpp.so.<version>         patched libvips (exports no glib symbols)
#
# Copy both into a consumer's node_modules/@img/sharp-linux-x64/lib/ and delete
# its @img/sharp-libvips-linux-x64 package. Stock sharp's own JS then loads the
# patched pair with no source changes — see README.md. PhotoStructure installs
# them from this repo's release assets via bin/patch-sharp.mjs.

# The addon needs to find the patched libvips sitting next to it, and must not
# be diverted to some other libvips-cpp.so with the same SONAME elsewhere in a
# consumer's tree.
#
# --force-rpath gets old-style DT_RPATH rather than patchelf's default
# DT_RUNPATH. The distinction is load-bearing: RUNPATH is consulted *after*
# LD_LIBRARY_PATH, RPATH *before* it. With RUNPATH, a stray LD_LIBRARY_PATH
# entry — or a leftover unpatched libvips-cpp.so elsewhere in the consuming
# project — silently wins over this co-located patched copy. RPATH always wins
# for our own NEEDED entry, whatever the consumer's environment looks like.
