Moving from 0.1 to 0.2

A 0.1 project builds with the 0.2 as it is: every new field is optional. A few things change on their own, though, and deserve a look.

Update

npm install docpensieve@beta   # while the 0.2 is in beta
npm install docpensieve@latest # once it is released

Through npx alone, npx docpensieve@beta runs the beta.

What	In 0.2
Search	A field in the header, and a page at `/search/` in each version
`sitemap.xml`	Written at the root of the site as soon as `siteUrl` is set
`robots.txt`	Written with it, when the site is served at the root of its domain
The stylesheet	Minified
Images	Their width and height are written; all but the first of a page load lazily
`theme.darkMode`	Now read: `'dark'` and `'light'` keep one scheme, `'class'` follows the system

Content pages still load no script: the search page alone does.

A page of yours at /search/ now stops the build: that address is the search page's. Rename your page, or set search: false.
theme.darkMode was accepted and ignored in 0.1. A value other than 'class' now takes effect — and an unknown one stops the build.
Your own robots.txt, if you published one next to the site, is now written by the build when the site sits at the root of its domain. Set sitemap: false to keep yours.

Field	Gives
`sidebar: 'sidebar.json'`	A menu written by hand, in each version's folder
`feed: true`	An RSS feed of the pages that carry a `date`
`versions[].logo`, `favicon`	A logo and a favicon of the version's own — a beta told apart
`search: false`	No search at all, if the site does not need one
