" scripts/test-keymaps-vim.vim — driven by scripts/test-keymaps-vim.sh.
"
" Pure-VimL keymap regression suite. Plain Vim's LSP path
" (vim-lsp + async.vim) talks to the server via timers, which won't
" reliably fire inside `vim -e -s` headless mode — so the cases here
" are restricted to the bindings whose RHS is implemented entirely in
" VimL (header/link nav, `o`/`O` bullet continuation, the wrap step
" of `<CR>`). LSP-roundtrip bindings (`<C-Space>`, `=`, `-`, …) get
" their coverage from the Neovim harness in scripts/test-keymaps.lua
" — same Lua codepath, same server.
