Ребрендинг дефолтного (не white-label) продукта «Trade-In» → «Мера» + inline-SVG логотип (буква М над размерной линией). Topbar MeraMark заменяет TI-бейдж, wordmark/крошки/футер/meta → «Мера». White-label бренды клиентов, сервисный термин «трейд-ин» в прозе OfferCard/HeroTransparency и code-идентификаторы /trade-in/ не тронуты. tsc 0 + build green.
