/**
 * Accessible Forms — front-end styles.
 *
 * Defaults are accessibility-first: a thick visible focus indicator, large
 * touch targets, errors that never rely on colour alone, and a layout that
 * reflows cleanly to 320px.
 *
 * EVERY colour and size below comes from a custom property on .aaf-form, and
 * the plugin writes those properties from Settings → Appearance as an inline
 * style that lands after this file. So a site owner brands the form from the
 * admin screen, and a theme developer only has to redeclare the tokens:
 *
 *     .aaf-form { --aaf-accent: #0b1f3a; --aaf-on-accent: #fff; }
 *
 * No rule here needs to be fought with !important.
 *
