/*
 * Wedding invitation + guest guide (EPIC-10).
 *
 * One invitation tied with a ribbon; under it, a stack of cards the guest
 * takes off one by one with a vertical swipe. Tokens are the photo app's
 * "Wedding Paper" palette (frontend/src/index.css), plus the ribbon, which
 * is sampled from the real chiffon on the printed invitations. Single
 * deliberate look, like the paper it imitates: no dark variant.
