+##Price estimate
+
+Rough figures in EUR, for the #Need list above. **Estimates, not live-checked
+prices** — the four docs/project-plan.md-sourced ones (GPU, ESP32 board, amp,
+speakers) are reused from that doc as-is; everything else is a typical-market-price
+guess for that exact product category, not pulled from the live Amazon listing (the
+search used to find these links doesn't return price data — click through and check
+before budgeting against this). All EUR figures assume roughly 1:1 with the USD
+prices these products actually list at; check amazon.de directly for real
+local pricing/VAT/shipping.
