/* ==========================================================================
   NKENG ATO Maxime Melaine, portfolio.
   Modernist design system: full-bleed ruled grid, zero radius, no shadows,
   Archivo only, one red accent.

   Two rule weights carry the whole layout:
     2px solid var(--color-text)          structural divisions
     1px solid var(--color-neutral-300)   hairlines inside a section
   Responsive behaviour comes from flex-wrap, flex-basis and auto-fit grids.
   There are no media queries in this file. Do not add any.
