/* ===================================================================
   Shipright.space — "Lumen" theme
   Light, premium, restrained. Near-white canvas, near-black ink, one
   deliberate Cobalt Violet brand accent (Galaxy S26 Ultra), navy for structure.
   Separation by hairline borders and whitespace, not
   glass or shadow. Synthesis of Samsung discipline + Promethean calm +
   OneScreen's purposeful accent.
   Order: reset, tokens, base, layout, components, portfolio,
          utilities, animations, media queries.
   Type: Archivo (headings) + Inter (body).
