Primary buttons hardcoded the dark text that reads on a mint accent. On Daylight the accent is a deep green, and dark text on it manages 3.6:1 — squinting territory. The colour that sits on the accent is now `--accent-text`: dark on the four themes where that reads best (7–10:1), white on Daylight (4.4:1, the better of the two). Modules can use it too; the guide lists it with the palette. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
