   These custom properties are the Midnight palette. Do not retint them.
   Status hues are reserved and unused on the pages; they stay defined so a
   later pass can mark a GPS warning without inventing a new color.

   Contrast (WCAG 2.1), checked with a relative-luminance script.
   Body text needs 4.5:1. Large text and UI boundaries need 3:1.
