/*
 * PlantOS — the brand site.
 *
 * Near-white paper, deep navy ink, one electric blue. The light in the page
 * comes from blurred blue orbs sitting behind the product shots rather than
 * from blocks of background colour, so the ground stays white and the screen
 * itself is the brightest thing on the page — which is the point.
 *
 * Display type is Heebo, set heavy and tracked hard negative. Hebrew has no
 * equivalent of the flared grotesk this is modelled on, and a serif would
 * read as editorial rather than as software; weight and tracking carry it.
 *
 * Shares its palette with the product (plantos-frontend/src/index.css). A
 * change to one belongs in the other.
