Vinted fee changelog

Initial verification from Vinted's official 'Buyer Protection fee on Vinted' help-centre article per market (GB, DE, FR, US) and each market's 'Is selling on Vinted free?' article as secondary corroboration. Confidence medium: the secondary source independently confirms selling carries no seller-side fee, but does not restate the Buyer Protection percentage or fixed amount, which comes only from the primary page. Vinted's GB page states the Buyer Protection fee as a range (3% to 8% + £0.30 to £0.80) rather than a single rate, unlike DE, FR and US which each state a flat 'usually 5% + [fixed fee]'; the range is modelled as separate minimum and maximum rules. Vinted Pro (business accounts) is out of scope for this pass: no official Vinted Pro fee schedule was crawled, so this file covers the standard, free selling schedule only.
