/**
 * Section: Build Time
 * Ported from .docs/mockup/css/howitworks.css lines 12-102 (.buildtime
 * through .bt-row .k) and the `.bt-layout` half of the page's pooled
 * responsive block (900px). Tokens only -- no hardcoded colours or sizes.
 *
 * `.bt-list`/`.bt-row` are rendered as <ul>/<li> rather than the mockup's
 * <div>s -- this is a genuine list of task/time facts, not a layout grid,
 * so it gets list semantics per section-architecture.md. The class
 * selectors below are unchanged from the mockup, so no rule here needed to
 * change: the theme's global reset (`* { margin:0; padding:0 }` plus
 * `ul, ol { list-style: none }` in base.css) already strips native list
 * chrome, and `.bt-list { display:flex }` / `.bt-row { display:flex }`
 * override the list-item default box, so the rendered result is pixel
 * identical to the mockup's div version.
