/* ════════════════════════════════════════════════════════════════════
   subscriber_v4.css — v300 — 20260507
   Unified design system for the subscriber portal.
   Inherits from admin_finance_v4 / admin_user_profile / staff_v2 patterns
   and adapts them to the subscriber-facing experience.

   Conventions:
   - All section gaps use --sub-section-gap (24px).
   - All cards use --sub-card-radius (18px) + --sub-card-padding (24px).
   - Brand accent for subscribers is solar amber + emerald, NOT admin purple.
   - dir="ltr" islands for any phone/IP/numbers (site-wide rule).
