/*
 * Cairn application stylesheet shell — Tailwind v4 source lives in
 * app/assets/tailwind/application.css and gets compiled to
 * app/assets/builds/tailwind.css by tailwindcss-rails. Propshaft serves the
 * build output (via `stylesheet_link_tag :app`); this file stays minimal so a
 * stale propshaft cache doesn't ship empty CSS in production if the build step
 * is skipped.
