Components
Every component in @sigx/zero, by tier. Each one renders a stable
data-scope / data-part / data-state anatomy and no styling; every page lists the
parts, their states and flags, the props, and what the shipped design systems wire.
Each component is its own subpath — import { Tabs } from '@sigx/zero/tabs' — and is also
re-exported from the package root. State is one two-way model prop;
every component composes the variant axes (color, size,
variant, axes, mods), which pass through as data-* attributes for a design system to
style.
