/* ============================================================================
   ATLAS REDESIGN — Plan & Billing (Brokerage) screen styles
   Ship-readiness Wave · 2026-07-03

   Prefix: .rd-bill. Tokens only (--r-*) so Calm (almanac) + Operator themes
   both work automatically. Calm enterprise billing surface — generous
   whitespace, ONE accent moment (the amber rule on the plan card), everything
   else quiet. Content scrolls with the page — no viewport-locked heights.
   Single column at 390px.
