V3: Portfolio Intelligence, Sealed Tracking & Dex/Collectr Feature Parity

  • Portfolio value history chart — sparkline with 7D/30D/90D/1Y toggle on your collection page, showing value over time like Collectr's 'stocks for cards'

  • Sealed Inventory (/sealed) — track booster boxes, ETBs, and sealed cases with cost-vs-value and per-item P&L

  • Set Detail Pages (/sets/[id]) — Pokédex-style set checklists with card images: owned cards in full color, missing cards grayed and silhouetted
  • Pokédex Completion Tracking — aggregate progress hero and per-set progress bars on /sets (inspired by DexTCG)
  • Smart Folders — create auto-rule folders like 'Gem Mint 9.5+', 'Last 30 days', 'Pokémon only' — membership auto-updates as your collection grows

  • Marketplace Integration — 'Sell' button on each collection card pre-fills a marketplace listing with card name, set, number, grade, and image
  • Multi-Currency Display — pick USD/EUR/GBP/JPY/CAD/AUD on your account page; all portfolio values convert on the fly

  • Glass-Style Bottom Nav (Android) — translucent surface with gold gradient top border, reordered: Home · Scan · Collection · Market · Account
  • 3 new tool cards on /tools — Sealed Inventory, PSA Submissions, Insurance Report
  • Short URLs — mastergrade.ai/go and /mg now redirect to the /links page
  • Security hardening — photos endpoint ownership checks, path traversal guard, ImageMagick resource limits, rate limits on /api/sets/[id], import field length caps, smart folder array bounds
  • Performance — 24h upstream cache on set detail API, perf indexes on collection_items + wishlist_alerts, removed 'unoptimized' from collection thumbnails (fixes slow photo loading)
  • SEO — layout.tsx metadata wrappers for /sealed, /submissions, /insurance; /insurance added to sitemap; wishlist invalid inline <title> removed
  • Accessibility — aria-busy on skeleton loaders, aria-labels on wishlist form inputs, useId() for Sparkline gradient ID
