+### Session 2026-03-25l — ProviderCard molecule (first molecule)
+
+**Agent(s):** Claude Opus (via conversation)
+
+**Work completed:**
+- Reviewed 3 Figma designs: Provider Cards (5503:44422), Service Venue (2997:83018), Map Pin Card (5369:140263)
+- Captured business context: verified vs unverified providers, Parsons partner strategy, map + list layout
+- Replaced generic "PriceCard" in registry with 3 specific molecules: ProviderCard, VenueCard, MapCard
+- Saved business context to auto-memory (project_listing_cards.md)
+- Created plan via /plan mode — component API, card structure, token plan, story plan
+- Created providerCard component tokens (`tokens/component/providerCard.json`): image.height, logo.size, footer.background/paddingX/paddingY, content.padding/gap — 7 tokens
+- Built ProviderCard molecule (`src/components/molecules/ProviderCard/ProviderCard.tsx`):
+  - Composes Card (interactive, padding="none") + Badge + Typography
+  - Verified variant: hero image (CSS bg-image cover), logo overlay (48px circle, absolute positioned, overlaps content), "Trusted Partner" badge (filled brand), capability badge
+  - Unverified variant: text-only, same content area + footer
+  - Footer bar: warm brand.100 bg, "Packages from $X" + ChevronRight
+  - Accessibility: aria-label on reviews, aria-hidden on decorative icons, alt text on logo
+  - All values from token CSS variables, no hardcoded hex
+- Created 9 Storybook stories: Default, VerifiedProvider, UnverifiedProvider, ListLayout (mixed), CapabilityVariants, EdgeCases, Responsive, OnDifferentBackgrounds, InteractiveDemo
+- Preflight passed all 5 checks
+- Logged D026-D030 in decisions log
+
+**Decisions made:**
+- D026: Molecules compose atoms via sx — no MUI theme overrides
+- D027: Image as URL string (CSS bg-image), logo as URL string (<img>)
+- D028: Logo 48px (not 75px Figma) for card width proportion
+- D029: Footer built in via startingPrice prop, not a slot
+- D030: verified is explicit boolean, not derived from imageUrl
+
+**Component status at end of session:**
+- **Done (7):** Button, Typography, Input, Card, Badge, Chip, Switch, Radio
+- **Review (1 molecule):** ProviderCard
+- **Planned (7 atoms):** IconButton, Icon, Avatar, Divider, ColourToggle, Slider, Link
+- **Planned (5 molecules):** VenueCard, MapCard, ServiceOption, SearchBar, StepIndicator, FormField
+- **Planned (5 organisms):** ServiceSelector, PricingTable, ArrangementForm, Navigation, Footer
+
+**Next steps:**
+- User to review ProviderCard in Storybook — especially ListLayout story for verified/unverified alignment
+- Build VenueCard molecule (simpler — always has photo, location, capacity, price)
+- Consider MapCard as a deferred item until map integration
