/* Royal Original design tokens (Email Template Examples brand book v1.0).
   Generated from docs/brand/tokens.json, the canonical data. Change values there first, then here.
   Naming per book p21: --color-{key}, --font-{key}, --font-size-{role}, --font-weight-{role}, --line-height-{role},
   --letter-spacing-{role}, --space-0..10, --radius-*, --shadow-*, --motion-*, plus layout aliases per breakpoint.
   Light only: the site has no dark theme (owner decision 2026-10-29), so the book's dark column is not used.
   Email previews never use these tokens: they keep their own colors. */
