/* Gold Network tier — MobileX "Priority Access" plans (#21).
     Activation tiles: Web/Views/Activate/Carrier/MobileXPlans.cshtml  (.pricing-box.is-gold + .gold-tier-header)
     Refill table:     Web/Views/Refill/RefillCarrier.cshtml           (.gold-tier-badge)
   Treatment chosen via design review (2026-06-04): a gold HEADER BAND ("Option B"), not a gold ring.

   This is a BRANDED-TIER treatment, deliberately kept in a different visual channel from the green
   PROMO treatment (promo-tile.css). Promo owns the card RING (box-shadow) + the top-right SAVE ribbon;
   Gold Network owns the TOP HEADER BAND + a gold-tinted price. A plan that is BOTH gold and promo
   composes cleanly: the gold header sits inside the green ring and the SAVE ribbon keeps its corner.
   The gold treatment never sets a border or box-shadow, so it cannot collide with the promo ring.

   Loaded site-wide from _Layout.cshtml right after promo-tile.css, so every class is namespaced
   (.is-gold / .gold-tier-header / .gold-tier-badge). Never reuse Bootstrap names — repo hard rule.
   Champagne -> amber gradient (not flat mustard) so it reads as premium metal, not a discount sticker. */

/* Full-bleed header band. .pricing-box carries NO horizontal padding (the inner sections do) and is
   overflow:hidden, so this first child spans edge-to-edge and clips to the card's rounded top corners
   with no negative margins. */
