Hue 226 (#ffff00) has a contrast ratio of 1.05 against the tangere-light
background (#fdfdfa), below the minimum-contrast = 1.1 set in the ghostty
config. Ghostty then substitutes the foreground for whichever of black or
white has more contrast, so against a near-white background that letter of
the model name rendered black.
Swap 226 for 184 (#d7d700, ratio 1.51 light / 9.60 dark) in the Opus ramp
and the unknown-model fallback, the only two palettes that used it.
