/**
 * digit-field.css — Ops UI Library: DigitField visual feedback
 *
 * Single rule that paints an input red while its current length is non-empty
 * but does not match any allowed lengths. Toggled by lib/digit-field.js.
 *
 * `!important` is required to override the default `.sl-input` background from
 * slider.js — slider form fields use rendering-specific selectors with higher
 * specificity than a plain class.
