/* ==========================================================================
   murmur — a living population feeling the arc market.
   Aesthetic: warm paper + ink, gallery / scientific-plot. Nothing neon, no
   glass cards, no tables. The artwork is the whole page; the UI floats on it.
   Palette tokens are live: app.js retints --paper / --accent with the market
   temperature, so the whole scene slowly warms (hot) or cools (cold).

   Performance note: the field canvas repaints every frame, so the floating UI
   deliberately avoids backdrop-filter and heavy blend modes (they would force a
   re-blur / re-composite of the whole scene each frame). Panels use a plain
   translucent fill; the grain overlay is static and normally composited.
