/* =============================================================================
 * components/form-field.css — labelled text-field primitive
 * =============================================================================
 *
 * Label-above-input pattern with a token-driven input surface: cream-400
 * border, --radius-lg, terracotta focus ring, peach error state (never
 * red — matches the learner dashboard's gravity-without-alarm rule).
 * Reusable across auth surfaces (login, password reset, invite accept,
 * 2FA verify), Profile field inputs in Phase 3 Commit 6+, and any later
 * tenant-admin form that needs a labelled text control.
 *
 * Applied via classnames on the widget's `attrs` in forms.py (see
 * apps/accounts/forms.py). The Django widget emits a standard <input>;
 * .form-field__input carries the visual contract.
 *
 * Structure:
 *   <div class="form-field [form-field--error]">
 *     <label class="form-field__label" for="…">Work email</label>
 *     <input class="form-field__input" id="…" …>
 *     <p class="form-field__error">…</p>    {# only when --error #}
 *   </div>
 *
 * Error signalling uses the peach scale (not --color-error). Red stays
 * reserved for destructive confirmations.
 * ============================================================================= */
