/* ===========================================================================
   Gurleen Kaur - portfolio
   ---------------------------------------------------------------------------
   Art direction follows the agreed reference: a black canvas, white type, one
   electric-lime accent, a geometric display face over a light humanist body
   face, and motion built on two easing curves at 0.3s / 0.7s.

   Contrast note: body copy clears 4.5:1, but a few small labels (carousel
   tabs, card numbers, scroll hints) keep the reference's 0.35-0.4 white to
   match it exactly, which is below WCAG AA. Raise them here if that matters more.

   Order: fonts, tokens, reset, utilities, page chrome, header, hero, marquee,
   intro, work, playground, capabilities, process, closing and footer, case
   study, forms, cursor, motion, responsive, reduced motion, print.
