and tooling — providing semantic tokens, selection ranges, and LSP
bridging for embedded languages (e.g., code blocks in Markdown).

+--- @brief
+---
+--- https://github.com/atusy/kakehashi
+---
+--- Tree-sitter-based language server that provides semantic tokens, selection ranges,
+--- and LSP bridging for embedded languages (e.g., code blocks in Markdown).
+---
+--- kakehashi works with any language that has a Tree-sitter grammar.
+--- Parsers and queries are automatically installed on first use
+--- when `autoInstall` is enabled (the default). This requires the
+--- `tree-sitter` CLI, a C compiler, and Git.
+---
+--- **You must specify `filetypes` in your call to `vim.lsp.config`** to
+--- restrict which files activate the server:
+---
+--- ```lua
+--- vim.lsp.config('kakehashi', {
+---   filetypes = { 'markdown', 'lua', 'rust', 'python' },
+---   init_options = {
+---     autoInstall = true,
+---     -- Optional: bridge LSP requests in injection regions
+---     languageServers = {
+---       ['lua_ls'] = {
+---         cmd = { 'lua-language-server' },
+---         languages = { 'lua' },
+---       },
+---     },
+---     languages = {
+---       markdown = {
+---         bridge = { lua_ls = { enabled = true } },
+---       },
+---     },
+---   },
+--- })
+--- ```
+
+---@type vim.lsp.Config
+return {
+  cmd = { 'kakehashi' },
+  root_markers = { 'kakehashi.toml', '.git' },
