   TT MAGNET — dark editorial, monochrome.
   Design tokens lifted from the reference build (kids-clothing-store-jet):
     · Instrument Serif for display, Inter for everything else
     · pure monochrome — near-black + neutral off-white, NO colour accent
       (photography supplies all the colour)
     · wide letter-spacing on small caps (0.2–0.25em)
   Inverted to a dark base per brief.
