/* ============================================================================
   GHOSTSIG theme
   ----------------------------------------------------------------------------
   Every visual decision lives in this file. app.js sets classes and text only,
   never inline styles and never a colour, so swapping the design means editing
   this file and nothing else.

   Deliberately single-theme. A neon page commits to one visual world, so there
   is no prefers-color-scheme block, but every colour, including the body
   ground, is painted explicitly so the page holds anywhere.

   References, one signature move each:
     Radicle:  border-radius 0, dashed borders, mono everything
     Aztec:    fragmented letter-spacing on the wordmark, dot-matrix labels
     Neon:     saturated triad, glow reserved for live values
