 * Ada Article — new template stylesheet (Ada Tech School blog redesign).
 * Loaded ONLY by custom-newdesign.hbs. Never reached by post.hbs / index / tag / page.
 *
 * Scoping discipline (verified by pre-deploy grep):
 *   Every selector starts with one of: .m-ada- / .l-ada- / .js-ada- / :root / @
 *   No bare element selectors. Element styling for article content is scoped
 *   under .l-ada-article-content table { ... }, etc.
 *
 * Reuses --ada-red from the existing global stylesheet (cascades fine since both load).
