+## Iteration 1 - 2026-02-04
+### Task: 1.1 Design Tokens Module
+### Status: COMPLETE
+### What was done:
+- Created `pathways_app/styles.py` with all design tokens from DESIGN_SYSTEM.md
+- Colors class: Heritage Blue, Primary, Vibrant, Sky, Pale blues + Slate neutrals + semantic colors
+- Typography class: Font family (Inter), sizes, weights, line heights for Display/H1/H2/H3/Body/Caption/Mono
+- Spacing class: XS(4px) through XXXL(48px)
+- Radii class: SM(4px) through FULL(9999px)
+- Shadows class: SM/MD/LG/XL shadow values
+- Transitions class: Color/Transform/Shadow/Opacity timings
+- Helper functions: card_style(), button_primary/secondary/ghost_style(), input_style(), kpi_card/value/label_style(), text_display/h1/h2/h3/body/caption/mono()
+- Layout constants: TOP_BAR_HEIGHT="64px", PAGE_MAX_WIDTH="1600px"
+### Validation results:
+- Tier 1 (Code): python -m py_compile PASSED, imports verified (Colors.PRIMARY = #0066CC, Spacing.LG = 16px)
+- Tier 2 (Visual): N/A (no UI component yet)
+- Tier 3 (Functional): Helper functions verified - return correct dict structures
+### Files changed:
+- Created: pathways_app/styles.py (408 lines)
+- Updated: IMPLEMENTATION_PLAN.md (marked 1.1 complete)
+### Committed: 2bd28f5 "feat: create design tokens module (styles.py)"
+### Patterns discovered:
+- Using classes with class attributes (not instances) works well for tokens
+- Helper functions returning dicts can include _hover and other pseudo-selectors
+### Next iteration should:
+- Start Task 1.2: Create app_v2.py with basic Reflex app skeleton
+- Create AppState class with minimal placeholder state
+- Set up single-page layout structure matching DESIGN_SYSTEM.md
+- Configure Reflex theme with design system colors
+- Verify `reflex run` compiles and shows page
+### Blocked items:
+- None
