+### Session 2026-03-30a — Tooling upgrades + workflow evaluation
+
+**Agent(s):** Claude Opus 4.6 (1M context)
+
+**Work completed:**
+- **Storybook addons:** Added `@storybook/addon-storysource` (story source code panel) and `@storybook/addon-a11y` (real-time axe-core accessibility checks)
+- **Playwright MCP:** Installed `@playwright/mcp` and registered as MCP server. Enables Claude Code to take screenshots of Storybook for visual verification. Available from next session.
+- **Workflow evaluation:** Comprehensive analysis of current capabilities, identified core gap (Claude Code cannot see visual output), researched solutions
+- **Antigravity research:** Investigated Google Antigravity IDE for visual polish workflow. Installed on system. Created `GEMINI.md` project rules file. User decided to pause on Antigravity for now and continue with Claude Code + Playwright MCP approach.
+- **GEMINI.md:** Created project rules file for Antigravity IDE, mirroring key conventions from CLAUDE.md (token access, atomic tiers, no hardcoded values)
+
+**Decisions made:**
+- Playwright MCP is the primary solution for visual verification gap — enables Claude Code to screenshot Storybook stories and self-correct visual issues
+- Antigravity available as secondary tool for visual tweaks but not primary workflow
+- Claude Code remains the primary tool for architectural/structural work due to custom skills, memory system, and accumulated project context
+
+**Open questions:**
+- User has refinement feedback from previous session that was partially overlooked — to be addressed next session
+- Some items from the user's original feedback across 15 steps were missed when compressed into D-A through D-H decisions
+
+**Next steps:**
+- Restart session to activate Playwright MCP
+- User to provide refinement feedback
+- Use Playwright MCP to visually verify changes as they're made
+- Address remaining P1s from previous session (radiogroup keyboard nav, dialog mobile fullscreen)
