Performance Fix

Systematically find and fix performance issues in $ARGUMENTS (or the whole app if no argument is given). Always measure first — never optimize blindly.

Step 1 — Measure baseline before touching anything

Run the production build and capture metrics before making any changes:

pnpm run build
pnpm run preview

Open the app in Chrome and capture:

• Lighthouse score (Performance tab → Run audit)
• React Profiler (React DevTools → Profiler → Record an interaction)
  • Note the components with the longest render times and highest render counts
