   PIIXI — product-surface extensions to Mad Panda tokens.
   Loaded after src/tokens.css. Adds Piixi-specific semantics:
   - signal green is the product accent (Mad Panda brand reserves it for Piixi)
   - 'warm-bone' for pendientes-de-revisión (NOT red, NOT alarming)
   - product-density type scale (legibility-first, not editorial)
