/* Docs layout and skin (platform decision 0020 §4), ported from design/Landing-02-Docs and 02b-Docs-phone.
   Tokens, type and components come from /css/*.css (@getorrery/styles). Committed by hand; everything else in
   landing/docs/ is written by scripts/site/build-docs.mjs. One page: wide = site bar + docs nav + article +
   index, only the article scrolls; narrow (<= 860px) = the 02b phone layout (docs bar, drawer, "On this page"). */
