Code for #187

/*
 * Haishoku Sōkan palette #187: CSS custom properties and Tailwind CSS v4 theme
 * Wada colors (Helvetia Blue, Grayish Lavender - B, Aconite Violet) are unchanged, from Sanzō Wada, A Dictionary of Color Combinations.
 * Numbered steps (bigger is darker) hold every value; role names such as
 * background or the -on, -ui, -text and -subtle variants point at a step.
 * Every value except the Wada colors is derived by Haishoku Sōkan from this
 * palette and is not a Wada color.
 * Derived values: CC0 1.0, no credit required.
 *
 * The @theme block at the end is for Tailwind CSS v4: place this file after
 * @import "tailwindcss"; for utilities such as bg-background. Without
 * Tailwind, browsers ignore it.
