/*
 * The design tokens: colour, type, radius, shadow. Nothing else lives here.
 *
 * ONE file, read by two things: the admin SPA, and the signed-out pages the
 * identity host renders on auth. (S9 decisions, 2026-09-26). Ascripto.Identity
 * embeds this exact file at build time rather than keeping a copy, so the
 * sign-in page and the app cannot drift into two slightly different products.
 *
 * Carried over from poc/12-signature-editor, where the palette was tried in both
 * themes and both editors.
 *
 * Theme (ux-plan, Cross-cutting): auto / light / dark. Dark is defined twice --
 * under prefers-color-scheme for "auto", and under [data-theme="dark"] for an
 * explicit choice -- so the toggle wins in both directions.
 *
 * Editor identity (U22): [data-mode="html"] retunes the chrome for the HTML
 * editor. The signature canvas reads --paper* only, which no theme and no mode
 * ever redefines (U11: the recipient's inbox is not themed by us).
