   paultan.org × Carro — "Sell your diesel car" funnel
   Theme: industrial / utility, rugged-modern. Dark asphalt/charcoal base with
   an industrial-amber fuel accent + pump-green confirm tone. Saira Condensed
   (display) + Saira (UI). Hero motif: a horizontal diesel→petrol fuel-cost
   comparison readout (NOT the car-value circular gauge). Tasteful hazard-
   stripe / pump detailing. Shares sell-landing.js — every JS hook (ids,
   .step, .step-progress, .sell-flow__thankyou, .faq-tab, [data-centre-*],
   .tac-dialog, .mobile-cta) is preserved and restyled here.
