+    Auto-close and auto-rename HTML/XML-style tags via Treesitter.
+
+    Why this exists: nvim-autopairs (see autopairs.lua) only handles brackets,
+    quotes and endwise pairs -- it never creates a closing tag. Its only
+    HTML-aware rule fires on <CR> when a close tag ALREADY exists after the
+    cursor, so it can re-indent a pair but cannot create one. This plugin
+    fills that gap: typing `<div` + `>` yields `<div></div>` with the cursor
+    in between, and `ciw` on an opening tag renames its closing counterpart.
+
+    Requires the matching Treesitter parsers. `html`, `vue`, `tsx` and
+    `javascript` are already in treesitter.lua's `ensure_installed` list, and
+    the plugin no-ops in filetypes whose parser is missing, so a fresh machine
+    just needs a restart after the parsers are installed.
