/*
 * SMS units page (phase 151). One stylesheet for BOTH homes of the page:
 *   - portal:     smsUnits.php                  (Bootstrap 4 portal chrome)
 *   - storefront: online-store/sms_purchase.php (storefront chrome)
 * Everything is prefixed smu- and sets its own fonts/sizes/colours, so neither host's
 * Bootstrap version or legacy CSS changes how it looks.
