Let the route explain the kind of work
A quick note on keeping developed writing, experiments, reference, and a guided path legible.
A publishing site collects several different tempos of work. A design decision may need a fully argued article. A running observation may only need three paragraphs. An interactive model needs room to be used, while installation details need stable reference pages.
Alkemist keeps those jobs visible in the URL. Blog is for developed writing; Logs is for short working notes; Labs is for things to operate; Docs is reference; and Book is a path where one chapter prepares the next.
The separation is modest, but it prevents a useful note from pretending to be an essay and prevents a tutorial from becoming an unfindable stream of posts. A site can choose which section labels appear in its navigation through src/lib/sections.ts.
