/* ShipSwipe — "Night Shift" visual identity
   A dark-first, nautical-editorial system for builders who ship after hours.
   Deep ink-navy base, sea-glass teal as the single highlight, warm brass for
   match/like energy. Refined SYSTEM SERIF display (Iowan Old Style / Palatino),
   humanist sans body. Soft layered depth, a faint chart-grid, tactile deck physics.
   Colors authored in oklch. Light + dark are first-class. No web fonts, no externals. */
