/* CryptoIndia — site styles
   ---------------------------------------------------------------------------
   Palette is taken from the product itself rather than picked fresh: #05070F is
   the app's Scaffold background, #00D4AA its primary, and the golds are lifted
   from the logo's chrome-and-gold mark. Gold is the deliberate odd choice here —
   fintech reaches for blue or acid green — but it is the brand's own metal, and
   it carries "premium" without the word.

   Type: Space Grotesk for display (instrument-like, slightly mechanical
   letterforms), IBM Plex Sans for prose, IBM Plex Mono for every price, symbol
   and condition. The mono is functional: tabular digits keep decimal points
   aligned down a column, which is how a trader reads a scanner.
