/*
 * Open, the qr-router design language, on the Open Exit tokens (DEC-030). The token block below is
 * a copy of the single source at docs/design/system/tokens.css (DEC-064): the declarations match it
 * exactly, and the backend design token parity test fails the build on drift.
 *
 * Kevin accepted the Open (I2) direction for the landing: one continuous white surface where
 * typography, space and thin rules carry the hierarchy, and no island or card surfaces. This file
 * extends that direction to the whole product. The rules are written out in
 * docs/design/2026-09-23-open-design-language.md; every class here is named there.
 *
 * Colours come only from the variables below. Dark mode follows the Graphite palette: Ink
 * page, Paper text, Mint accent, never Teal on Ink.
