- pinterest home (hero + masonry, "load more"); old list view at /index3/
- new pages: /about, /blog, /legal, /find/, /finds/, custom 404
- footer collection links now clickable; "founded" stat replaces "updated"
  in the masthead

 - **Sources catalog** at `sources.json` with per-source fetch strategy (`webfetch` / `curl` / `skip`) and the `/sources` page rendering a 3-column card stream with a "Recent finds" sub-list per card
 - **Strict find visibility**: find items are reachable only via the superposts that reference them, the `/sources` cross-reference, or direct URL — they don't crowd the home feed, tag pages, or category pages
 - **Backlinks** computed at build time: each find page lists every superpost that references it; promoted finds show a forward link to the review; reviews show a "← First surfaced…" backlink to their originating find
-- **Unified chronological feed** on the home page across reviews + finds (superposts) + posts
+- **Newspaper-style masthead** on every page: live entry-count + last-updated stats on the left, large serif "Unique" wordmark centered between thin rules, About/Blog nav on the right; per-page italic subheader ("A small log of delightful things.") with last-updated date on listing pages
+- **Pinterest-style home page**: hero card for the latest review plus a 3-column masonry grid of remaining reviews with a "Load more" reveal; old plain-list home preserved at `/index3/`
+- **Unified chronological feed** at `/index3/` across reviews + finds (superposts) + posts
+- **SEO-friendly site footer** with Browse / Collections (live counts) / About link columns and a centered legal line; consistent 76rem page width across the entire site (article prose constrained to a comfortable reading measure inside the wider layout)
 - Reviews render as two-line index entries: bold name + muted subtitle (`Cotypist` / *Autocomplete that lives everywhere on your Mac*)
 - Auto-generated `/categories/<name>/` and `/tags/<name>/` listing pages — finds excluded by design
+- **Amazon affiliate handling** in `src/lib/affiliate.ts`: outbound links to Amazon (`amazon.com`, `amzn.to`, `a.co`, `smile.amazon.com`) get the configured tracking ID appended automatically; the link gets `rel="sponsored"`, an "Affiliate" badge appears next to it, and a one-line disclosure is shown beneath. Add additional marketplace IDs (e.g. `amazon.co.uk`) to the `AMAZON_TAGS` map when needed
+- **SEO surface**: single `<SEO>` component owning canonical, Open Graph, Twitter Card, and JSON-LD; per-page structured data (`Review`, `BlogPosting`, `Product`, `Article`, `CollectionPage`, `ItemList`, `BreadcrumbList`, `WebSite`, `Organization`); auto-generated `sitemap-index.xml` (excludes `/grid/` and `/index3/`); RSS feed at `/rss.xml`; `robots.txt`; static OG image fallbacks under `/public/og/`; promoted finds canonical to their review
+- Custom 404 page with recent-reviews and navigation fallback
 - Light/dark mode via `prefers-color-scheme`
 - No JavaScript shipped to the client
 - Static build, deployable anywhere
