/* GOTCHA -- the rickroll takeover. See web/js/gotcha.js for what this is,
   how it is triggered, and how to delete it.

   Written in the product's own tokens on purpose: the joke only lands if
   the alert looks like a real LINEHOUND surface right up until Rick. Every
   colour here is an existing reserved token (--v-money for the price
   moment, --v-warn for caution, --live for the analytical cyan) rather
   than a new palette, so it reads as this product having a breakdown
   rather than as a different website. */
