/**
 * Form field — labeled text input with error/hint text.
 * Also includes divider and text link helpers.
 * Uses --bb-* tokens so it automatically reflects the active theme.
 *
 * Usage:
 *   <div class="bb-field">
 *     <label class="bb-field__label" for="email">Email</label>
 *     <input class="bb-field__input" id="email" type="email" />
 *     <p class="bb-field__error">Invalid email.</p>
 *   </div>
 *
 *   Add class "bb-field--error" to .bb-field to highlight its control border.
 *   Non-text controls use .bb-field__control to inherit validation only.
 *
 *   <div class="bb-divider"><span>or</span></div>
 *
 *   <button class="bb-link">Forgot password?</button>
