/* ==========================================================================
   SSA BOSS — Design tokens
   Benchmark: Zoho Books / Zoho CRM / Pipedrive — clean whitespace,
   restrained palette, subtle elevation, confident typography.
   Signature idea kept from the original pass: this is a system of
   record for a sourcing/logistics business, so Task IDs read like
   manifest numbers (monospace, bracketed) against an otherwise plain,
   fast, businesslike interface. One accent color, used sparingly.
