" development/tests/test-config-vim.vim — Vim counterpart of
" test-config.lua. Dumps the Vim client's `initialization_options` payload
" (nuwiki#lsp#settings()) for the same two scenarios as the Neovim harness,
" as byte-identical `key=value` lines, so both can be diffed against the
" shared golden development/tests/config-expected.txt.
"
" "nvim == golden" and "vim == golden" together prove Vim/Neovim config
" parity for everything the server consumes.
