/* ============================================================
   OB — Verdict Preview Teaser — scoped component styles
   Phase 2 / Plan 02-02 / BRAND-08

   Lifted near-verbatim from design-handoff/vt-component.css.
   All token references rewritten to --ob-* prefix matching
   the live child-theme global-variables.json token IDs.

   Net-new token: --ob-warning-fg (AA-safe amber on warning-bg)
   sourced from gcid-ob-warning-fg added to global-variables.json.

   Dual delivery:
     - Front end: enqueued via wp_enqueue_scripts in functions.php
     - VB iframe: injected via ?inline import + IIFE in index.jsx

   No warning-fg hex literal here — always use var(--ob-warning-fg).
