/* ═══════════════════════════════════════════════
   Stadium patch — Billing screen (invoices + credit notes)
   Loaded AFTER css/app.css. Scoped to `.billing-page`
   (class added on the page container in js/billing.js).
   NOTE: the invoice table itself is styled by the runtime
   <style id="billing-styles"> injected from js/billing.js
   (it lands after this file in document order, so the
   canonical table rules live there). This patch covers the
   page shell, empty state and error state only.
