   Violet Sovereign. Source of truth: KNOWLEDGE/brand/BRAND.md, exported to
   brand-tokens.css (--vs-*), which MUST be loaded before this file.

   Everything below is an alias onto a --vs-* token. Don't put literal colours
   here, and don't put them in the rules further down either — if you need a
   colour that isn't in this list, add it to BRAND.md first.

   Dark is the default; light comes free via [data-theme="light"] in
   brand-tokens.css, because every alias resolves through --vs-*.
