 * App CSS only. The design package (ui.css, tokens.css, fonts.css) is vendored unchanged under
 * app/assets/design/ and linked before these files (app/views/layouts/_head.html.erb).
 *
 * Rules for everything in app/assets/stylesheets (enforced by spec/design/stray_values_spec.rb):
 * - only design tokens (var(--…)); no raw colours;
 * - no px, except in app/layout.css, which holds only the 1280-width overrides of the --app-* tokens.
