4.78.0

1 Nov 2026

kit-layout.css: the fluid scale, the layout primitives and a classless base (plan L54 K1/K2). A file of its own, after kit.css (2.5 KB brotli); a page that uses none of it loads neither.
- The fluid scale: --step--2 … --step-5 for type and --space-3xs … --space-3xl for spacing, by clamp() between 320 and 1240 px (16 → 18 px base, ratio 1.2 → 1.25). No breakpoints.
- Eight primitives that lay out by their own width: .ov-stack, .ov-cluster, .ov-sidebar (--end), .ov-switcher (all side by side or all stacked, never two and one), .ov-grid, .ov-rail, .ov-cover, .ov-frame. Set by --gap, --min, --side, --item, --ratio.
- .ov-base: plain HTML (headings, text, links, lists, quotes, code, tables, details, forms) looks finished on the site's theme. Every selector is inside :where(), so a site's own rule always wins.
- Documented in docs/kit.md; test/kit-layout-chrome.test.js measures each in Chrome at 320, 1280 and 1920 px.
