+- [x] Favicon restored from the original WordPress site icon via the Wayback Machine (2026-10-23):
+      `favicon.ico` (16/32/48), `favicon-32x32.png`, `icon-192.png`, `apple-touch-icon.png` (180),
+      `icon-270.png` in `public/`. Previously the wide logo was used, and `/favicon.ico` 404'd.
 - [ ] Per-page 1200×630 OG images; `BaseLayout.astro` emits one shared fallback `og:image`.
 - [ ] `robots` meta wired to a `noindex` frontmatter flag. `/thank-you/` is excluded from the
       sitemap but emits no `noindex` meta tag.
