Guarded by tests: every pair must meet 4.5:1, and foregrounds must stay
pure white/black unless deliberately hand-tuned. The enum-sync test's
exhaustive switch is hoisted into a shared helper covering the triple.

Each picker color now ships a (background, foreground, outline) triple. The foreground is the text/icon color to use on the background fill: pure white or pure black per color, whichever contrasts more. No single theme-wide text color is readable across all 20 fills (in light mode every fill fails 4.5:1 against Material's default label colors; in dark mode 8 do in the other direction) — a per-color pick passes AA on all 20, worst case sahara at 4.59:1. Guarded by tests: every pair must meet 4.5:1, and foregrounds must stay pure white/black unless deliberately hand-tuned.
