+- **Lead-Back Guarantee** — suppliers can claim credits back for non-responding leads

+  `refund_lead_guarantee()` in credits.py, "Lead didn't respond" button on unlocked
+  lead cards (visible 3–30 days after unlock). Migration 0020 adds `guarantee_claimed_at`
+  and `guarantee_contact_method` columns to `lead_forwards`.
+- **Supplier page CRO restructure** — `/suppliers` page reordered to lead with value
+  before pricing (Why Padelnomics → Lead-Back Guarantee → lead preview → social proof
+  → pricing). All CTAs changed from "See Plans & Pricing" to "Get Started Free".
+- **Static ROI line** — one-sentence ROI callout near pricing grounded in
+  `research/padel-hall-economics.md` data (4-court project = €30K+ contractor profit).
+- **Credits-only callout** — below pricing grid: "Not ready for a subscription? Buy
+  a credit pack and unlock leads one at a time."
