/* ===========================================================================
   HOLLOW VEIL — design system
   Owned by: nobody (shared). HUD / Keel / Lobby each own their own stylesheet
   and must build on these tokens and primitives rather than redefining them.

   Visual language: a cold, failing industrial station lit by a dying red dwarf.
   Interiors are desaturated blue-grey. The star is amber. The Hollows are void
   black with violet lattice. Everything is thin lines, hard angles, and light
   that looks like it costs power to produce.
