/* ==========================================================================
   Rebate calculator (".rcalc") — CORPORATE cards only.

   Ported from the approved standalone designs
   (Downloads/New/Newcards/IMTIAZ Corporate World Mastercard.html and
   IMTIAZ Corporate Executive Mastercard.html -> the `.rcalc`, `.rb`, `.calc`
   and `.rcalc-head` rules), recoloured to BCFC brand:
   blue #004a98, accent #005189, red #f32735, grey #53575a.
   The design's champagne/navy palette is NOT reproduced; no greens, no yellows.

   This is NOT rewards-calc-v2.css. That file is the consumer cards' 4-slider
   POINTS calculator (.calc2). This one is the 3-slider corporate CASHBACK +
   annual-bonus rebate widget. They never appear on the same page.

   RULES OBSERVED (both have broken pages in this repo before):
   1. EVERY custom property used here is DECLARED on the .rcalc root itself,
      so the component cannot lose its tokens when it is reused on a page whose
      stylesheet scopes tokens to a page class.
   2. EVERY var() also carries a literal fallback, so even if the declaration
      block were lost the component degrades to the correct colour instead of
      inheriting the link blue through `color: inherit`.
   3. Every selector starts with .rcalc, so nothing leaks out of the widget and
      the generic design class names (.rb, .calc, .rate-foot) are not used.
