;;; test-prog-webdev--format-wiring.el --- Verify the TS/JS formatter is wired -*- lexical-binding: t; -*-

;;; Commentary:
;; Webdev's binding is installed via `local-set-key' inside the
;; `cj/webdev-keybindings' hook, fired from typescript-ts-mode,
;; tsx-ts-mode, js-ts-mode, and web-mode. The format command itself
;; (`cj/webdev-format-buffer') is defined in prog-webdev.el and shells
;; out to the `prettier' binary.
;;
;; Three checks:
;;   1. `cj/webdev-format-buffer' is fboundp.
;;   2. The hook installs C-; f → `cj/webdev-format-buffer' in the
;;      buffer-local map.
;;   3. The `prettier' executable is on PATH.

;;; Code:
