/*
 * naluma-pages — shared CSS for verify + legal surfaces.
 *
 * Design tokens mirror the Naluma email-template palette and align with
 * naluma-design-system/build/css/tokens.css. Every hex below corresponds
 * 1:1 to a `--primitive-color-*` in the design system (e.g. `--color-bg`
 * = `--primitive-color-warm-white`). Spacing/radius primitives match
 * `--primitive-{spacing,radius}-*` 1:1. Easing matches
 * `--primitive-easing-default`.
 *
 * TODO(ds-import): replace these redeclarations with a direct `@import`
 * of naluma-design-system/build/css/tokens.css once the pipeline can
 * resolve a cross-repo import (today, naluma-pages is a self-contained
 * subdirectory of naluma-app and doesn't depend on naluma-design-system).
 *
 * Mobile-first. Max content width 720px. Accessible focus rings +
 * 44×44 touch targets. Loaded as styles.<8charHash>.css — long-cached
 * and immutable.
