/* =================================================================
   FEEDBACK STUDIOS — "Signal"
   Art direction: a dark, expensive editorial canvas where TYPE is the
   hero. A generative iridescent backdrop and glossy capsule renders
   carry the brand spectrum (violet -> blue -> emerald) against near-
   black. Satoshi is the workhorse; Instrument Serif is the editorial
   accent, set in the brand gradient. Emerald is the single signature
   accent reserved for "the number" (revenue / results).
