   CARDINAL LABS — bright build, 2026-08-23

   Palette derived from the BRAND, not from anyone else's site. The previous
   build sampled its whole colour system out of a screenshot of a client's
   website, which made Cardinal Labs' identity a function of a wrap shop's
   paint. Cut. Cream ground, warm dark ink, and ONE accent — the cardinal.

   Contrast measured, not assumed, on #F4F1EA:
     --ink 16.28:1 AAA · --muted 5.37:1 AA · --cardinal 4.69:1 AA
     --slate 3.44:1 — NON-TEXT MARKS ONLY, never type
     white on --cardinal 5.29:1 (the button label)
