# dev-python/xhtml2pdf is a soft upstream dep used for PDF report
# export; it cascades into a large pyHanko dep tree. Skipped here —
# SasView runs without it; only the PDF export feature breaks.
#
# 6.1.x pinned pyausaxs==1.0.4; 6.2.0 unpinned it. We now depend on the
# real dev-python/pyausaxs (the AUSAXS C++ wrapper, resolves 1.2.0) so
# SasView's SANS Debye path runs the accelerated backend instead of the
# pure-Python fallback (ausaxs_sans_debye.py still try/excepts, so a
# missing/broken lib degrades gracefully). x86_64-only: the wheel ships a
# prebuilt libausaxs.so, matching sasview's ~amd64-only KEYWORDS.
# verified 2026-07-31
