/* Siliconcordat / Moissanite Labs — design tokens (Direction A: Carbon–Silicon Cut)
   Same house as Weft (Moissanite Labs), a different room: a crystal chamber, not a loom.
   Dark only for v1. Text is always a flat colour; gradients live on surfaces and atmosphere only.
   Fonts are self-hosted from assets/fonts (SIL OFL 1.1). Paths are relative to this file. */
