/*
 * Buttons
 *
 * BEM-style component classes for buttons previously emitted by
 * `button_class` in app/helpers/links_helper.rb. The helper has been inlined;
 * the class names below are now written directly in ERB.
 *
 * Usage:
 *   class="btn btn--primary btn--medium"   (default style + size)
 *   class="btn btn--secondary btn--large"  (size only affects .btn--print today;
 *                                           other styles bake in their own padding)
 *
 * Cascade order matters: sizes are defined BEFORE styles so style padding wins.
 * Styles that omit padding (e.g. .btn--print) defer to the size modifier.
