"""Build the CNX Vinyl business plan .docx, in its two versions (October 2026).

    python build_plan.py                 -> ../CNX-Vinyl-Business-Plan-A.docx and -B.docx
    python build_plan.py A               -> ../CNX-Vinyl-Business-Plan-A.docx
    python build_plan.py B out.docx      -> Plan B to a custom path

Plan A (~180M THB) and Plan B (~215M THB) share every chapter; the content modules
switch the plan-specific text with plan_variant.pick(). Images are resolved relative
to docs/ (the parent of business-plan/).
