   Fran Olivares — person surface of Olivares AI
   One house with the product: Matte Black, warm white, one scarce orange.
   Space Grotesk (display) + Inter (body) + JetBrains Mono (record keys).
   Palette mirrors olivares.ai tokens (brand-brief/BRAND-MANUAL.md; AA pairs
   #f08000-on-dark / #b45500-on-light are measured there, not invented here).
   Signature: the audit ledger — rows of record, exactly one row flagged orange.
