Thanks @matyix — closing this as superseded rather than merging, since the link has landed in the meantime.

#8 ("Enhance README with blog posts and TOC", merged 2026-02-02) added a dedicated ## Related Blog Posts section carrying this same article, so main already points at it. That is also why this PR now shows as conflicting: both changes edit the same spot right after the intro paragraph.

The two differ only in route, and both resolve to the same live page:

	URL	resolves to
main (from #8)	blog.riptides.io/introducing-libsigv4-…	→ riptides.io/blog/… — 200
this PR	riptides.io/blog-post/introducing-libsigv4-…	→ same page — 200

So there's nothing broken to fix, and merging would leave the post linked twice under two URLs. Reopen if you'd rather main used the direct riptides.io/blog-post/… form — that's a one-liner against the existing entry and doesn't need this branch.
