/*
 * credit.css — Unified Credit V1 UI. Layers on top of styles.css (admin light
 * theme). Reuses .admin-* tokens; adds credit-specific components. Scoped under
 * .credit-page so it never leaks into the game/usage pages.
 *
 * Design direction: light "fintech dashboard" — disciplined hierarchy, three
 * clearly separated entitlement lanes (credit / VIP / DeepSeek) each with its
 * own accent, provider-colored catalog groups, dense but readable ledger.
 * Credit is the hero unit; VND is always secondary.
