/*
 * Perchari marketing site palette.
 * Warm and light, taken from the brand mark (brand/README.md): the gold tile
 * the robin sits on, its one red accent, and the near-white the horizontal
 * lockup is flattened onto. Deliberately the inverse of the Revres landing
 * (deep navy) -- same layout, different product.
 *
 * Gold accent + red highlight + warm ink over near-white.
