site: ui/ux refresh, seo pass, find/lists indexes, 25 new finds

- newspaper-style masthead (stats | "Unique" | About/Blog) on every page
  with per-page italic subheader + last-updated date on listing pages;
  sitewide 42rem reading width
- 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
- centralised SEO component with per-page json-ld (Review, BlogPosting,
  Product, Article, CollectionPage, ItemList, BreadcrumbList, etc.);
  @astrojs/sitemap + @astrojs/rss; robots.txt; promoted finds canonical
  to their review
- memoize getSiteStats() so the masthead/footer counts don't multiply
  per-page build cost
- 25 new daily-finds captures

+    <h2>Privacy</h2>
+    <p>
+      Unique doesn't run analytics, ad pixels, or third-party trackers. The
+      site sets no cookies of its own. Your visit produces a normal web-server
+      access log entry (IP, user-agent, referrer, requested path) at our
+      hosting provider, kept only for the rolling window needed to investigate
+      abuse and outages, and never sold or shared.
+    </p>
+    <p>
+      Outbound links go to third-party sites that have their own privacy
+      practices; we have no control over those.
+    </p>
+
+    <h2>Affiliate disclosure</h2>
+    <p>
+      Some outbound links — most often to Amazon — are affiliate links. If you
+      buy something after clicking one, we may earn a small commission at no
+      additional cost to you. Affiliate links are marked with an
+      <strong>Affiliate</strong> badge and a one-line disclosure on each page
+      where they appear. Affiliate revenue does not influence what we cover or
+      how we cover it; nothing on this site is sponsored or paid placement.
+    </p>
+
+    <h2>Trademarks &amp; copyright</h2>

+      respective owners and appear here under fair use for editorial review
