/* =========================================================================
   Stake for CAKE - design system

   The palette is taken from the pixel-art cake in the favicon: sponge cream
   (#FEFFC1), butter-gold crumb (#FDDC73), terracotta crust (#A66458) and
   cocoa crust shadow (#7D3C2A).

   LIGHT-FIRST: cream ground, cocoa ink, chocolate-brown for every interactive
   thing, butter gold reserved for fills and highlights. Gold measures only
   1.26:1 against the cream ground, so it can never carry text or a thin mark -
   --gold-text is the legible stand-in, --gold-fill is the literal butter gold.

   A cocoa dark theme is kept under [data-theme="dark"].

   Every ink token clears 4.5:1 on every surface in its own theme (worst is
   4.80). Chart hues are a SEPARATE validated set (--viz-*) - never reuse a UI
   accent as a data colour.
