/* ===========================================================================
   DCPR CALCULATOR — interface styling.

   Design language is taken from krishnaprojects.com so the tool and the site read as
   one practice: the same beige ground, brass accent, dark-brown ink and chakra mark.

   This is a TOOL, not a document, so it is built to be operated rather than read:
   summary before detail, state encoded in shape and colour as well as number, and
   verdicts legible at a glance across a table.

   SEMANTIC COLOUR IS SEPARATE FROM THE BRAND ACCENT. Brass is identity; green/amber/red
   mean GO / CAUTION / NO-GO and are never used decoratively. A verdict must never be
   mistakable for styling.

   NOTE: this file contains no calculation constants. Every number shown comes from the
   API; the front-end formats but never computes. Guard-enforced.
   =========================================================================== */
