;;; test-prog-webdev--classic-and-web-mode-hooks.el --- Classic js + web-mode setup hooks -*- lexical-binding: t; -*-
;;; Commentary:
;; The config audit found the webdev setup hooks attached to the
;; tree-sitter modes only, so a grammar-unavailable fallback to classic
;; js-mode silently lost indent/keys/LSP, and web-mode got the format
;; key but none of the promised setup (no company/flyspell/LSP in HTML
;; buffers). These tests pin the classic js-mode hooks and the
;; web-mode setup hook, plus the html-language-server guard that keeps
;; LSP silent on machines without the server.
