/* ============================================================================
   Business & Client API documentation — modern component layer
   Scoped to /documentation/business-api/* pages (loaded per-page).
   Reuses the site brand tokens (--color-brand #1a2f6e, Inter/Roboto) and the
   existing .api-doc-* endpoint cards; adds a two-column TOC layout, tabbed
   code samples, callouts, method tags for PATCH/PUT, steps and comparison
   tables. Light theme only (matches the rest of the site).
