+### Session 2026-03-25n (continued) — IconButton, Divider, Link atoms
+
+**Agent(s):** Claude Opus (via conversation)
+
+**Work completed:**
+- Built IconButton atom — wraps MUI IconButton with FA theme overrides:
+  - 3 sizes reusing Button height tokens (sm 32px, md 40px, lg 48px)
+  - Rounded rect shape (borderRadius.md), brand hover colours, focus ring
+  - 4 colour options: default, primary, secondary, error
+  - 5 stories including CommonUseCases (card toolbar, dialog close, nav toggle)
+- Built Divider atom — wraps MUI Divider with FA border token:
+  - Horizontal/vertical orientation, fullWidth/inset/middle variants
+  - Text children support (MUI built-in)
+  - 6 stories including InContent and NavigationList patterns
+- Built Link atom — wraps MUI Link with FA brand tokens:
+  - Copper colour (brand.600, 4.8:1 contrast) by default
+  - Underline on hover, focus-visible ring, fontWeight 500
+  - 7 stories including Inline (body text), Navigation, FooterLinks
+- Added MuiIconButton, MuiDivider, MuiLink overrides to theme
+
+**Decisions made:**
+- IconButton uses rounded rect (borderRadius.md) not circle — consistent with Button. Circle can be achieved with sx if needed.
+- Link defaults to underline="hover" — always-underlined links feel heavy in FA's clean aesthetic, but the underline is important for discoverability so it appears on hover.
+- No new component tokens — IconButton reuses Button tokens, Divider uses palette.divider, Link uses palette colours.
+
+**Component status at end of session:**
+- **Done (8):** Button, Typography, Input, Card, Badge, Chip, Switch, Radio
+- **Review (3 atoms):** IconButton, Divider, Link
+- **Review (2 molecules):** ProviderCard (v2, audit 17/20), VenueCard (critique 33/40)
+- **Planned (3 atoms):** Icon, Avatar, ColourToggle, Slider
+- **Planned (4 molecules):** MapCard, ServiceOption, SearchBar, StepIndicator, FormField
+- **Planned (5 organisms):** ServiceSelector, PricingTable, ArrangementForm, Navigation, Footer
+
+**Next steps:**
+- User to review IconButton, Divider, Link in Storybook
+- Build ServiceOption molecule (core arrangement flow interaction)
+- Consider building Navigation organism (now that IconButton + Link are available)
 - Remaining P3s: InfoOutlinedIcon sizing in ProviderCard, image loading placeholder, accent bar 3px→4px
