/*
 * Propshaft serves each file independently; it doesn't concatenate or
 * follow @import statements. The Tailwind v4 build output lives at
 * `app/assets/builds/tailwind.css` and ships nothing by default. An
 * explicit `<%= stylesheet_link_tag "tailwind" %>` in the layout
 * is the missing wire — without it, every page is rendered without
 * the design system (dark-first Tailwind palette, font utilities,
 * everything from `@theme`).
