/* Shared brand layer — locusconsulting.com /brand/brand.css
   Cross-identity tokens and web fonts. Each identity namespaces its own tokens;
   nothing here overrides an identity's local values.
   Identities: /brand/locus (parent), /brand/allele (product), /brand/stravon (product),
   /brand/chirograph (product), /brand/variorum (product), /brand/almoner (product, gated Draft).

   Family grammar, the accent registry, the copy system, and each identity's ratification
   record now live consolidated in one canonical package: docs/brand/locus-brand-package.md
   (card #831). This file remains the source of truth for token VALUES; that document is the
   source of truth for what the tokens mean, cite, and where the family's shared rules (shared
   navy/cream, one-mark/one-accent-node grammar, type ramp, trope avoidance) are recorded. */
