One copy of the series, and it is the published one

One copy of the series, and it is the published one `docs/blog/` held sources for posts that live at skippednote.dev, rendered by a pipeline this repository does not contain. Two copies of the same prose is a chance for one to be wrong, and the repo copy was the one that could not be read properly anyway — GitHub draws neither the `press-diagram` blocks nor the `[!TLDR]` callouts the posts are written with. So the README links the series and nothing here duplicates it. Nothing is lost: the posts are published, and these files stay in the history of the commit that added them if the wording is ever wanted back. The provenance is worth stating once even though the files are going. Every figure in those posts — the 77-second Glacier restore, the 608 lost objects, the 1,280 index jobs never claimed, the 302 a delivery token got when the tenant check came out — was checked against this repository before it was written down, and several were narrowed when the check disagreed with the first draft.
