/*
 * Form controls on design tokens — light/dark automatic. Text-like controls
 * (.input/.textarea/.select) share a look; choices, switch, range, and file
 * inputs follow. The error state flips to danger via .is-invalid /
 * [aria-invalid="true"]; native controls (checkbox/radio/range) use
 * accent-color, and selects keep their native chevron so it tracks the theme's
 * color-scheme.
