/* ==========================================================================
   IMATNOTE — design system layer (v2)
   ==========================================================================

   Purpose
   -------
   The original `itm-*` system lives in the Customizer's Additional CSS
   (131 classes, ~24 KB). It is NOT replaced here: existing pages keep
   working exactly as they do today. This file adds a documented, reusable
   layer on top of it for the Phase 1 commercial pages — Home, Pricing,
   Product, FAQ, Contact — and gives later pages a single place to migrate
   into.

   Load order note: the Customizer CSS is printed after theme styles, so
   anything here that must beat an older `itm-*` rule is namespaced under
   `.itmx` rather than fighting it with `!important`. New markup opts in by
   putting `itmx` on its wrapper.

   Design intent
   -------------
   White ground, deep navy ink, generous vertical rhythm, hairline rules
   instead of stacked cards. The brand blue is an accent, not a texture:
   it appears on links, on the small labels above a heading, and on the
   primary CTA. Buttons are deliberately scarce — three per page at most.

  /* --- brand ----------------------------------------------------------- */
  /* Deep blue rather than the brighter #2563EB used in the older itm- rules.
     The value is pulled towards the header's own button colour (#025BAC) so
     a page CTA and the header CTA read as the same brand rather than two
     different blues, and darkened from there so it sits closer to navy.
     8.4:1 against white, so it passes AA both as a text colour and as a
     button fill with white text. */
