/* ==========================================================================
   Museum of Fantasy Sports — case study

   Shares the portfolio's typefaces and structural rhythm, but inverts the
   surface: the portfolio is paper in daylight, this is a gallery after closing
   time. Brass is the only added colour, used for catalog numbers and rules.

   This page describes the app; it is not the app. The application itself is a
   separate Next.js deployment mounted at /fantasy.
