"""Supported OS platform matrix for molecule tests.

Single source of truth for the platform list used by both:
- ``scripts/ci/distribute_molecule.py`` (CI parallel matrix)
- ``scripts/molecule_all.py`` (local sequential runner)

Keeping this in a dedicated module avoids cross-imports between
dev tools and CI scripts.
