What a pack contains
Thirteen headings, and the same thirteen every time: register, palette, type, texture and surface, components, hero, responsive, motion tokens, signature motifs, the signature element, micro-interactions, bans, and the traps the reference carries. Alongside it ships a token CSS file to copy verbatim and a React reference kit that renders the states a token layer cannot describe — hover, focus-visible, disabled, selected.
Why the ratios are computed
A production site is a real source and an imperfect one. Across this library, references were found putting white text on a fill at 2.9:1, secondary copy at 2.5:1, and a focus ring composited to 1.3:1 against a 3:1 floor. Each pack keeps the measured hue and moves only lightness until the pairing clears, and states the correction with its number at the declaration — so a derived value can never later be read as a measured one.
