+# UI System First Pass Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the first pass of the app-wide UI system and migrate the highest-impact frontend surfaces to the agreed typography, color, icon, layout, button, feedback, and AI content rules.
+
+**Architecture:** Centralize design decisions in token and common widget files, then migrate pages by replacing local hardcoded visuals with shared module visuals and components. Keep this pass focused on visible consistency and maintainability without adding the full accessibility-mode feature yet.
+
+**Tech Stack:** Flutter, Riverpod, shadcn_ui Lucide icons, flutter_markdown.
+

+- [ ] Convert user header to no-frame layout with settings on the right.
+- [ ] Keep health dashboard as a light panel.
+- [ ] Convert common functions to a two-column light matrix without heavy per-item cards.

+
+### Task 5: Profile, Health Archive, Diet, Device
+
+**Files:**
