# Pixelfed only handles common web formats (jpeg/png/gif/webp) plus modern avif/heic and jpeg-xl. 
# We enable exactly those delegates and explicitly disable every other loader.
#   - gif     : load uses libvips' bundled libnsgif, save uses bundled cgif, so no giflib dev package is required.
#   - heif    : AVIF/HEIC read+write via distro libheif -> aom/dav1d.
#   - jpeg-xl : JXL read+write via distro libjxl.
#   -Ddebug   : off, and we strip for a lean runtime library.
