/* Bot Trade Reconciliation Report — marketing site
   Design: a trustworthy financial-document feel. The product IS a report, so the report ledger is the
   hero. Serif headings (document voice), system sans body, real monospace for the ledger. Restrained
   cool-paper palette; the single teal accent is spent sparingly; green/red/amber are reserved as
   accounting semantics only. Fully offline: system fonts, no external requests, no scripts required. */
