What's included

Distribution (FIS-40)

• npm run build:zip produces a clean dist zip containing only runtime files (manifest.json, background.js, content.js, offers-content.js, popup.html, popup.js) — no tests, docs, or node_modules.
• Rewritten INSTALLATION.md as a non-developer walkthrough with per-OS unzip steps and troubleshooting.
• Bumps manifest.json to 1.4.0.

Pricing correctness (FIS-38)

• Offer extraction parity bundle with CI gate to prevent regressions between offer-page and listing scrapers.

Offer labels (FIS-71)

• Offer type and condition now render as separate fields — results show Used - Very Good, Used - Like New, New, etc. instead of a collapsed string.

Debug UI (FIS-72)

• Dropped the "All Offers Display" debug column from the all-prices table; it duplicated data already shown in the row expansion.

Docs (FIS-65)

• Added a user-facing how-to for the cheapest-copy flow.

Scope

• Supported: amazon.com wishlists at amazon.com/hz/wishlist/....
• Not supported: amazon.ca, amazon.co.uk, non-wishlist pages.

Known follow-ups

• D2 Chrome Web Store listing: tracked as FIS-41.
• Changelog + versioning policy docs: tracked as FIS-66 (PR #8).
