None — all pages load correctly, no broken content.

⚠️ Important (2 — both FIXED)

  1. Commodities index missing 18 commodities — FIXED in commit 6eba05d
    • Added: ammonia, ethanol, feeder-cattle, graphite, hydrogen, lean-hogs, live-cattle, manganese, oats, orange-juice, potash, rare-earth, rhodium, rice, rubber, soybean-meal, soybean-oil, vanadium
    • Added new “Livestock” category section
  2. Price data anomalies — FIXED in commit 6eba05d
    • coffee low_52w was 278.65 (above price 270.50) → fixed to 220.0
    • rice high_52w was 1,383.0 (absurd for $11.09 ETF proxy) → fixed to 14.5

💡 Nice-to-have (3)

  1. Proxy price duplicates — jet_fuel/diesel, manganese/iron_ore, graphite/rare_earth share identical prices because they use the same ETF/stock proxies. Consider adding unique proxies or noting “(proxy)” in the unit display.
  2. Unit display says “/share” for many proxied commodities — e.g., cobalt shows “$14.18/share” instead of a commodity-native unit. Could be confusing for users expecting $/lb or $/tonne.
  3. No dedicated price chart element detected — The Puppeteer check didn’t find a static chart DOM element. Charts may be rendered via JS canvas on interaction. Verify chart renders on user-facing browsers.
