/* Friendli public site — landing + legal pages.
 *
 * COLOUR DISCIPLINE — the point of this file.
 *
 * The brand is a violet-to-pink gradient. Used as a surface treatment it turns
 * a company site into a toy: gradient headline, gradient slab behind the hero,
 * gradient chips with nothing in them. So the rule here is that the gradient
 * belongs to the LOGO, and to exactly one deliberate panel colour — nowhere
 * else. Everything that used to be gradient is now either flat ink, the single
 * accent, or a real illustration.
 *
 * That leaves the page carried by neutrals, which are biased a few degrees
 * toward violet rather than being pure grey, so they read as chosen and as
 * part of the same family as the mark.
 *
 * The illustrations are white line art (shipped with the app's onboarding), so
 * they need a dark ground in BOTH themes. --panel is that ground, and it is
 * also the page's one saturated moment.
 *
 * Type: Figtree for display — geometric and rounded, which is what the mark
 * is — and Inter for body, the face the app itself bundles, so site and
 * product read as one thing.
