Locale provider (en default, persisted) + EN/SV switcher in header; converted header + landing sections + catalog/sources/order-flow/most-of-portal to useT({en,sv}). Fixed two partial conversions (forskott TRUST object/tuple map; kallor undefined ALL + raw object renders). tsc 0, build green. Remaining: admin/* + a few partials.
