/* FIPO Miner website — Claymorphism structure on the app's dark Copper theme.
   Plain static CSS: no frameworks, no external requests.
   Dark Copper palette (matches the FIPO Miner app): near-black background,
   dark copper cards, gold accents, warm cream text. Clay cards keep their
   puffy rounded shape with layered soft shadows, adapted to dark mode:
   a subtle warm top highlight plus a deeper soft shadow below — no white
   glare, no light backgrounds anywhere. */
