   Type: Fraunces (display) / Inter (body), self-hosted variable woff2.
   RULES BAKED IN HERE:
   - The wordmark is NEVER live text — always the SVG asset (brand doc).
   - No font-variation-settings anywhere in this file (brand doc).
   - Clay rose is a micro-accent: <=5% of any page, never a background wash.
   - Compliance-critical content (prices, Tier 1) is static HTML; nothing in
     this stylesheet may hide, collapse, or de-emphasise a .disclosure block.
