Pinned: primary = #007aff. Everything else is generated.
Anchor preserved exactly. The published value already satisfied the contrast contract, so the solver left it untouched.
9/9 semantic checks passed.
- Apple's guidance is to use an accent colour deliberately rather than covering the interface with it, and to provide adaptive semantic colours for both appearances.
- The preset therefore reads as neutral and clean with a blue accent, not as "everything is Apple blue".
- System Blue cannot carry white or near-black text at 4.5:1, so the solver normalizes the anchor. That normalization is reported on the brand page rather than hidden.
