/* ============================================================
   DMBS Finance — Delta Mobile Business Solutions
   Design system
   ------------------------------------------------------------
   Brand colours:
     Ash  #C6C3B5  — soft neutral (backgrounds, dividers)
     Red  #FF0000  — accent only (buttons, rules, highlights)
   Because pure red is an alert colour, it is used sparingly as
   punctuation; a deep charcoal carries text and dark surfaces
   so the red stays deliberate and the brand reads as trustworthy.
   ------------------------------------------------------------
   NOTE: variable names below describe a ROLE (e.g. --dark-800),
   not a literal colour, so the whole theme can be retuned here
   without touching the rest of the stylesheet.
   Type: Cormorant Garamond (display) / Source Sans 3 (body)
   Signature: the double brand rule — a paired hairline in red.
