   NORTH WATCH — styles.css
   A Scandinavian timepiece, presented like one.

   Palette:  warm charcoal #101012 / graphite #161619 / ivory #ECE9E1
             titanium #A8AAAC / warm grey #8C8B87 / machined red #C1272D
   Type:     Jost (display + labels, light weights, wide tracking)
             Newsreader (editorial serif body)
             Space Grotesk is reserved for the dial itself (script.js)
   Motion:   slow, precise, mechanical — nothing decorative.
