 - Treat `src/modules/dashboard` as a long-lived operational module. New high-level KPI, alert, queue, and shortcut surfaces should compose into it rather than spawning disconnected landing pages.
 - Any non-filter lookup UI must be implemented as a searchable picker or autocomplete; do not use long static dropdowns for operational datasets such as items, customers, vendors, or document-linked records.
 - Inventory items expose both cost and sell price. Downstream sales document entry should default from the item price field rather than requiring duplicate price maintenance.
+- Future vendor-facing purchasing flows should follow the same searchable-lookup rule and shared document/totals model already used by sales.
 - Shipping, sales, and future purchasing PDFs should be rendered through the backend documents module and shared Puppeteer pipeline rather than ad hoc frontend-only exports.
 - Preserve the current dense operations UI style on active module pages: compact controls, tighter card padding, and shorter empty states unless a screen has a clear reason to be more spacious.
