/*
 * Chill CRM marketing site.
 *
 * Colour, radii, shadow and typeface come from the product's own token layer
 * (design/tokens.ts) so the site and the app read as one system rather than two
 * products with similar logos. One deliberate departure: the app's type scale
 * tops out around 15px because it is a dense working surface, and that is far
 * too small for a page whose job is to be read across a room. The scale below
 * is the landing's own; every colour is the product's.
