Форма из #2377 рендерилась только в недостижимом legacy HeroTransparency/
HeroSummary; /trade-in/v2 — единственный живой прод-роут. Новый v2-native
LeadForm.tsx переиспользует useCreateLeadMutation as-is, портирует
валидацию/state-machine из HeroTransparency (не JSX), монтируется после
результата оценки (hasEstimate=true) вне scaled artboard.

Refs #2395, #2377

+// LeadForm — «Оставить заявку на трейд-ин» v2-native card (issue #2395: fixup
+// of #2377 — the working lead form only existed in the dead HeroTransparency/
+// HeroSummary legacy tree, unreachable from the live `/trade-in/v2` route,
+// which redirects everything else. This is the v2-native mount).
+//
+// Reused AS-IS (per #2395 DoD): `useCreateLeadMutation` (trade-in-api.ts) +
+// `TradeInLeadInput`/`TradeInLeadResponse` types — backend is untouched and
+// already live (`POST /api/v1/trade-in/lead`). The state machine / validation /
+// submit-handler shape is ported from HeroTransparency.tsx (idle → submitting →
+// success/error, phone regex mirroring the backend's `_PHONE_PATTERN`, explicit
+// ФЗ-152 consent) — but the markup/styling below is a fresh v2 HUD card built on
+// `tokens.ts`, not the legacy `.hero-lead*` CSS classes (those stay in
+// trade-in.css, unused by this component).
+//
+// Critical fixup carried over from the #2377 code review: the submit <button>
+// must NEVER receive the `disabled` attribute from validity state — only from
+// `leadMutation.isPending`. A `disabled` button does not dispatch a submit
+// event, so an invalid attempt would silently no-op instead of running the
+// handler and showing a hint. The form has `noValidate` and every submit
+// (valid or not) goes through `handleSubmit`, which surfaces an inline
